The technical solution relates to radio communications, and in particular to methods one-way radio communication between mobile objects, routes which have a common starting point.

There is a method of satellite communication (see, for example, Owhali, Niestetal, Usarc, Hardon Aguilar. Radio communication. Edited Avelona. - M.: Hot line - Telecom, 2001, s-279), namely, that transmit radio signals from the first movable object, take these radio signals on an artificial Earth satellite, transmit the radio signals from artificial Earth satellite, receive these radio signals on the second movable object, transmit radio signals from the second movable object, take these radio signals on an artificial Earth satellite, transmit the radio signals from artificial Earth satellite, receive these radio signals on the first movable object.

This method allows a great range of radio communication between moving objects on the Earth's surface or near it, regardless of their routes, however, requires removal of radio communication satellites in earth orbit and motion control and operation, which complicates the method.

However, the considerable height of the orbits of satellites (from hundreds of kilometers in systems with low earth orbits to tens of thousands is ilometres in systems with high-elliptical and geostationary orbits - see, for example, Umoristi, War, Lamnidae. Future satellite communication systems. - M.: Hot line - Telecom, 2000, p.71) require on the space station and mobile objects transceiver devices with large capacity, equipped vysokonapolnennyh antennas.

However, increasing the power transmitting devices causes the deterioration of their mass and size parameters, decreased immunity of the various on-Board radio-electronic means, as well as the reduction of electromagnetic safety of people on mobile objects.

The above drawback in combination with disabilities create antennas with higher gain leads to an increase in the geometric space occupied by this system with radio (local coverage of the earth surface by a single beam satellite repeater reach hundreds of kilometers in diameter - see ibid, p.78-110), which reduces the efficiency of the method in the simultaneous operation of multiple radio systems.

The term "volume of geometric space" describes one of the three major (along with the bandwidth and time) components of the RF space communication system (see Naagin. Topical issues of monitoring in the Russian Federation is tion. - M.: Radio and communication, 2000, C.11-12).

There is a method of radio communication between aircraft (see, for example, Pascalidou, Paisano. The maintenance of avionics. The Handbook. - M.: Transport, 1990, p.88-92), namely, that transmit radio signals from the first aircraft, take these radio signals on the second aircraft, transmit radio signals from the second aircraft, take these radio signals on the first flying machine.

This method does not require solving complex problems inherent in satellite radio, and allows a great range of radio communication between aircraft performing flight at high altitudes on arbitrary paths.

However, the communication distance between the low-flying aircraft significantly decreases as a result of the influence of reflection of electromagnetic waves from the Earth's surface (see, for example, theoretical foundations of radar. Edited Vaitulevich. - M.: Soviet radio, 1978, s).

To increase the range of radio communication it is necessary to increase the capacity of on-Board transceiver stations and the orientation of their antennas.

However, increasing capacity on-Board transceiver stations causes the deterioration of their mass and size parameters, decreased immunity of the various on-Board p is dielectronic funds as well as the reduction of electromagnetic safety of people on the aircraft.

The above drawback in combination with disabilities create antennas with higher gain leads to an increase in the geometric space occupied by the communication system, which reduces the efficiency of the method in the simultaneous operation of multiple radio systems.

Meeting the technical challenge is to improve mass and size parameters transceiver stations mobile objects, routes which have a common starting point, increasing the noise immunity of the various on-Board radio-electronic means, the increase of electromagnetic safety of people on the moving objects, the reduction in the geometric space occupied by the radio system, and therefore increase the efficiency of the method in the simultaneous operation of multiple radio systems based on the implementation of the radio using discharged from the moving objects in low-intermediate transceiver stations, are equipped with omnidirectional antennas, and discharged intermediate transceiver station at the end of the Radiocommunication destroy.

The solution of the technical problem in the way Radiocommunication between under igname objects routes which have a common starting point, namely, that transmit on the specified operating frequencies of the radio signals from the first mobile object are specified operating frequencies of the radio signals on the second movable object is achieved by the fact that since the time of the first removal of the first movable object from a common starting point by a distance defined by the given ranges of validity radio station, located on the first movable object and the intermediate transceiver stations, the first mobile object shall reset the intermediate transceiver stations at intervals along the range defined by the given ranges of the transmitting steps and intermediate transceiver stations, time to first remove the second movable object from a common starting point by a distance defined by the given ranges of the transmitting steps and intermediate transceiver stations, from the second mobile object shall reset the intermediate transceiver stations at intervals along the range defined by the given ranges of the transmitting steps and intermediate transceiver stations, and radio transmission from the first mobile object on the second movable object consists, if the reset intermediate transceiver stations operate with both moving objects, you accept transferred from the first mobile object signals on each of the group last reset with the first movable object intermediate transceiver stations and transmit them, accept transferred from each of the groups last reset with the first movable object intermediate transceiver stations radio signals on each of a group of other intermediate transceiver stations dropped from the first moving object during the time interval preceding the time interval of the reset of the specified group last reset with the first movable object intermediate transceiver stations, and transmit them, in the same way carry out reception and transmission of radio signals with other groups dropped from the first movable object intermediate transceiver stations in the direction of transmission of the radio signals from the reset intermediate transceiver stations during the later time intervals to reset during the earlier time intervals, accept transferred from each of the groups of the first discharged from the first movable object intermediate transceiver stations radio signals on each of the first group dropped from second podvijenog the object intermediate transceiver stations and transmit them take transmitted from each of the groups of the first discharged from the second mobile object intermediate transceiver stations radio signals on each of a group of other intermediate transceiver stations dropped from the second movable object during the time interval following the time interval is reset from the second mobile object groups of the first intermediate transceiver stations, and transmit them, in the same way carry out reception and transmission of radio signals with other groups dropped from the second mobile object intermediate transceiver stations in the direction of transmission of the radio signals from the reset intermediate transceiver stations within the earlier time intervals to reset during the later time intervals, taken on the second movable object by radio signals are radio signals transmitted from each of the groups last reset from the second mobile object intermediate transceiver stations, and if the reset intermediate transceiver stations operate only with the first movable object, the receiving transmitted from each of the groups of the first discharged from the first movable object intermediate transceiver stations radio signals carry on the second movable object, if the reset sub the internal transceiver stations shall only from the second movable object, the reception is transmitted from the first mobile object signals is carried out on each of the groups of the first discharged from the second mobile object intermediate transceiver stations, at the end of radio communication between mobile objects destroy thrown from moving objects intermediate transceiver station.

The method consists in the following.

Consider a situation in which the first movable object 1 is a ground vehicle, the second movable object 2 is low-flying aircraft, for example, helicopter, or airship.

The term "low flying aircraft" is generally accepted (see, for example, the Radio system. Edited by Prof. Umetalieva. - M.: Higher school, 1990, s). The second movable object 2, in particular an aircraft is flying at low levels, if the condition (see theoretical bases of radar. Edited Vaitulevich. - M.: Soviet radio, 1978, s):

where C is the speed of light; ha- the height of the first transmitting antenna 33 radio transmitting station 3, located on the first movable object 1; hb- the height of the first receiving antenna 34 a receiving station 4, the placement is Noah on the second movable object 2; d is the distance between the first mobile object 1 and the second movable object 2.

The expression (1) is true, if the condition of mirror reflection of radio waves from the underlying surface (see ibid., s):

where ψ - angle slip; δ - the height of the irregularities of the underlying surface.

For definiteness, let us assume that the surface on which the Ground surface is a mirror reflecting the horizontal plane, i.e. condition (2) is performed.

The first moving object 1 is moving only on the underlying surface.

On the first movable object 1 is placed radio transmitting station 3 and M intermediate transceiver stations 5 numbers m=1,2,... ,M, where m is a positive integer. On the second movable object 2 is placed a receiving station 4 and N intermediate transceiver stations 5 with n=1,2,... ,N, where n is a positive integer.

In the General case, the first movable object 1 and the second movable object 2 at each point of the reset can be reset on more than one intermediate transceiver stations 5.

Let us assume that the first movable object 1 and the second movable object 2 at each point of the reset discharge only one intermediate transceiver station 5.

Bol is e early time points reset intermediate transceiver stations 5 with the first movable object 1 are in the intermediate transceiver station 5 with lower numbers:

where tmtμ - time reset m-th μ th intermediate transceiver stations 5, respectively; μ =1,2,... ,M be positive integers.

On the first movable object 1 the interval taconduct from the time, in which the first movable object 1 was in General the initial clause (1).

Earlier time points reset intermediate transceiver stations 5 from the second movable object 2 are in the intermediate transceiver station 5 with lower numbers:

where tnand tv- time reset n th ν th intermediate transceiver stations 5, respectively; ν =1,2,... ,N be positive integers.

On the second movable object 2, the reference time tbconduct from the timeat which the second movable object 2 was in General the initial clause (1).

In General, moments in timeandcan not match.

Last reset from the first movable object 1 intermediate transceiver station 5 is an intermediate transceiver station 5, the discharge of which is carried out in the most recent point in time:

where mmax=1,2,... ,M

Last reset from the second movable object 2 intermediate transceiver station 5 is an intermediate transceiver station 5, the discharge of which is carried out in the most recent point in time:

where nmax=1,2,... ,N.

The set of intermediate transceiver stations 5 discharged from the first mobile object 1, break conditionally on the I groups.

The set of intermediate transceiver stations 5 discharged from the second movable object 2, break conditionally on J groups.

Each intermediate transceiver station 5 can be part of only one group.

In the i-th group of the intermediate transceiver stations 5 discharged from the first mobile object 1, the number of Qiintermediate transceiver stations 5 in the General case of arbitrary, but is limited by the condition

where i=1,2,... ,I is a positive integer.

In the j-th group of the intermediate transceiver stations 5 discharged from the second movable object 2, the number of Qjintermediate transceiver stations 5 in the General case of arbitrary, but is limited by the condition

where j=1,2,... ,J is a positive integer.

We assume that all groups of the intermediate receiving the transmitting stations 5 contain the same number of intermediate transceiver stations 5:

Therefore, M and N is a multiple of Q.

In this regard, the number of groups of intermediate transceiver stations 5 discharged from the first movable object 1 and the second movable object 2, equal to, respectively:

Conditional split discharged from the first movable object 1 intermediate transceiver stations 5 groups is carried out in accordance with the formula:

where m is the number of intermediate transceiver stations 5, included in the i-th group.

Conditional split discharged from the second movable object 2 intermediate transceiver stations 5 groups is carried out in accordance with the formula:

where n is the number of intermediate transceiver stations 5 included in the j-th group.

The discharge from the first movable object 1 intermediate transceiver stations 5 of the i-th group takes the following time interval:

The discharge from the second movable object 2 intermediate transceiver stations 5 j-th group takes the following time interval:

The group last reset with the first movable object 1 intermediate transceiver stations 5 which incorporates both the last reset of the intermediate transceiver station 5. Their number is determined by the formula:

The group last reset from the second movable object 2 intermediate transceiver stations 5 includes the last reset of the intermediate transceiver station 5. Their number is determined by the formula:

Will accept first that

If the condition (2) the range of the m-th reset with the first movable object 1 intermediate transceiver station 5, except for the first discharged from the first movable object 1 intermediate transceiver station 5 (m=1), is determined by the formula (see ibid., s-410, formula (14.10), (14.20), (14.30))

where Rm)- power radio signals transmitted from the m-th reset intermediate transceiver station 5; Pm-1 pminsome threshold value, which characterizes the sensitivity of the m-1 intermediate reset transceiver station 5; hmhm-1- the height of the second transmitting antenna 66 m-th and the second receiving antenna 50 (m-1)-th reset intermediate transceiver stations 5, respectively.

The range of the first discharged from the first movable object 1 intermediate transceiver station 5 is equal to

where-the power of radio signals transmitted from the first discharged from the first movable object 1 intermediate transceiver station 5;some threshold value, which characterizes the sensitivity of the first discharged from the second movable object 2 intermediate transceiver station 5;,- the height of the second transmitting antenna 66 is first discharged from the first movable object 1 and the second receiving antenna 50 is first discharged from the second movable object 2 intermediate transceiver stations 5, respectively.

Gave the ability actions last reset from the second movable object 2 intermediate transceiver station 5 is equal to

where- power radio signals transmitted since the last reset with the second movable object 2 intermediate transceiver station 5; Pb pminsome threshold value, which characterizes the sensitivity of the receiving station 4 of the second movable object 2;- the height of the second transmitting antenna 66 last reset from the second movable object 2 intermediate transceiver station 5.

The range of radio broadcast stations 3 of the first movable object 1 is equal to

where Ra)- power radio signals transmitted from the first mobile object 1;some threshold value, which characterizes the sensitivity of the last reset with the first movable object 1 intermediate transceiver station 5;- the height of the second receiving antenna 50 last reset with the first movable object 1 intermediate transceiver station 5.

Under the height of the antenna understand the distance to under the antenna point of the underlying surface.

In General, the height hathe location of the first transmitting antenna 33 transmitting when ancie 3 varies in the range of h a minto ha max. The minimum value of the height ha minis achieved when the first moving object 1 is located on an underlying surface, and is determined by the characteristics of the structures and layout of the first movable object 1 and the radio station 3. The maximum value of the height ha maxdoes not exceed the sum of the values of ha minand maximum flight altitude Hbut maxthe first movable object 1.

In this case, the first movable object 1 is a ground vehicle, and therefore ha min=ha max.

The height hbthe location of the first receiving antenna 34 a receiving station 4 is changed in the range of hb minto hb max.The minimum value of the height hb minis achieved when the first moving object 1 is located on an underlying surface, and is determined by the characteristics of the structures and layout of the first movable object 1 and a receiving station 4. The maximum value of the height hb maxdoes not exceed the sum of the values of hb minand maximum flight altitude Hb maxthe first movable object 1.

Height hmthe location of the second receiving antennas 50 and second transmitting antennas 66 discharged from the first movable object 1 intermediate transceiver stations 5 range of values of hm minto hm max. The minimum is the value of height h m minis achieved when m-I intermediate transceiver station 5 is located on an underlying surface, and is determined by the design features of this intermediate transceiver station 5. The maximum value of the height hm maxcorresponds to the time reset m-th intermediate transceiver station 5 with the first movable object 1 and does not exceed the value of ha max.

Height hnthe location of the second receiving antennas 50 and second transmitting antennas 66 discharged from the second movable object 2 intermediate transceiver stations 5 range of values of hn minto hn max. The minimum value of the height hn minis achieved when the n-th intermediate transceiver station 5 is located on an underlying surface, and is determined by the design features of this intermediate transceiver station 5. The maximum value of the height hn maxcorresponds to the time of discharge of the n-th intermediate transceiver station 5 from the second movable object 2 and does not exceed the value of hb max.

Expression (1), (2) and (19)-(23) are approximate and do not take into account the geometry of the first movable object 1, the second movable object 2 and the intermediate transceiver stations 5.

Considering the above, we assume that for all m and n fair equality

From expressions (19)-(22) it follows that under the conditions(18), (24)-(27) the minimum range of the intermediate transceiver stations 5 equal

Then we assume that Q>1; M and N are multiples of Q.

For given values of P[Izl]Pprminand hmingiven the formula (28) range intermediate transceiver stations 5 set equal

The range of radio broadcast stations 3 specify the given ranges of action of the intermediate transceiver stations 5, for example, by the formula:

The routes of movement of the first movable object 1 and the second movable object 2 have a common initial point O.

In General, when the traffic on their routes, the first moving object 1 and the second movable object 2 can make a stop at arbitrary time intervals. In addition, in the General case, the first movable object 1 and the second movable object 2 can start moving on their routes at any timeand.

Assume that the first movable object 1 perpetrated is on the underlying surface rectilinear motion from a common starting point Oh, located on the x-axis (figure 1); the motion is constant velocity Vaalong the x-axis in the direction of in the direction of decreasing values of x; the maximum distance from a common starting point to a first movable object 1 is equal to da max andcharacterizes the length of the route of the first mobile object 1.

The second movable object 2 exercises from the common starting point Of the vertical height hb maxand then performs a horizontal flight at a height of hb maxwith constant velocity Vbalong the x-axis in the direction of in the direction of increasing values of x; the maximum distance from a common starting point to a second movable object 2 is equal to db maxand characterizes the length of the route of movement of the second movable object 2.

While the implementation of the method lies in the fact that transmit radio signals from the first mobile object 1, take these signals to veronadina the object 2.

Distances from a common starting point to a first mobile object 1, which discharge the intermediate transceiver stations 5, can be measured on the first movable object 1 using inertial or Doppler systems reckoning (see Aeronautical radionavigation: a Handbook. Edited Ass. - M.: Transport, 1990, p.6-8).

Distances from a common starting point to a second movable object 2, which discharge the intermediate transceiver stations 5, can be measured on the second movable object 2 using inertial or Doppler notations p is t (see ibid, p.6-8).

and

When the previously specified characteristics of the motion of the second movable object 2 reset the n-th intermediate transceiver station 5 is carried out in time

and

where- vertical lifting of the second movable object 2 from the common starting point Of the height hmax.

Formula (36) is due to the fact that the intervals in range Δ dndetermine the maximum possible distance between two intermediate transceiver stations 5 discharged from the second movable object 2 in the next time.

Formula (37) is due to the fact that the range of db mindetermines the maximum distance from the second movable object 2 to the total initial point O corresponding to the time tb min.

In the General case, the first movable object 1 and the second movable object 2 can make movement difficult routes. In particular, they may first be removed from the common initial point O, and then adapted Atisa to him, then again removed and closer, etc. With the first movable object 1 and the second movable object 2 may repeatedly pass through a common starting point and, therefore, repeatedly placed him at distances less than da minand db minrespectively. However, the reset intermediate transceiver stations 5 with the first movable object 1 is not carried out only until the time of the first removal of the first movable object 1 from a common initial point O, the distance da min. From this point in time with the first movable object 1 discharge intermediate transceiver stations 5 intervals range defined by the given ranges of validity transmitting station 3 and the intermediate transceiver stations 5, and the intermediate reset transceiver stations 5 is carried out and if the result of movement of the first movable object 1 along the route distance common starting point On will again become less than the value of da min.

For the second movable object 2 is similar: reset intermediate transceiver stations 5 from the second movable object 2 is not carried out only until the time of the first removal of the second movable object 2 from a common initial point O, the distance db min.This time with W the cerned movable object 2 discharge intermediate transceiver stations 5 intervals in range, defined by the given ranges of validity transmitting station 3 and the intermediate transceiver stations 5, and the intermediate reset transceiver stations 5 is carried out and in that case, if the motion of the second movable object 2 on the route distance common starting point On will again become less than the value of db min.

If the wind speed is negligible, the velocity Vaand Vbthe movement of the first movable object 1 and the second movable object 2 is also so small that they do not cause significant disturbance of air masses, the trajectory of the fall intermediate transceiver stations 5, you can take vertical. While the aerodynamic properties of the structures of the intermediate transceiver stations 5 should not have any special features that cause a significant deviation of the trajectories of falling from a vertical.

After falling on the surface of the intermediate transceiver station 5 remain motionless.

The factors k2and k3take into account the possible inaccuracy of the scatter intermediate transceiver stations 5, due to the influence of various factors.

Since the timeandthe beginning of movement of the first dignaga object 1 and the second movably what about the object 2, and their velocity Vaand Vbin the General case are different, there are four characteristic cases:

When the movement of the first movable object 1 and the second movable object 2 routes, the length of which is equal respectivelyandperformed all four conditions (38)-(38). In each moment of time is only one of the specified conditions. In addition, due to the irreversibility of time, if it is one of the conditions (38 b)-(38, y), the condition (38) will not occur; if it is, the condition (38, g), then none of the conditions (38)-(38) also will not come. Thus, from the above it follows that the method can be carried out only in one way.

In the first case, (38, (a) neither of the first movable object 1 or the second movable object 2 reset intermediate transceiver stations 5 do not exercise. The implementation of the method in this case considered above.

Consider the implementation of the method in cases (38 b)-(38, g), which corresponds to the reset intermediate transceiver stations 5 with the first movable object 1 or/and the second movable object 2.

If, in accordance with condition the (38, g) resetting the intermediate transceiver stations 5 is carried out with the first movable object 1 and the second movable object 2, the method consists in the following.

From the first movable object 1 transmit radio signals. Take transmitted from the first mobile object 1, the signals on each of the last group (m=(imax-1)Q+1, (imax-1)Q+2,... ,mmax) discharged from the first movable object 1 intermediate transceiver stations 5 and pass them. Take transmitted from each of the last group (m=(imax-1)Q+1, (imax-1)Q+2,... ,mmax) discharged from the first movable object 1 intermediate transceiver stations 5 radio signals on each of the other groups (m=(imax-2)Q+1, (imax-2)Q+2,... ,(imax-1)Q) intermediate transceiver stations 5 discharged from the first movable object 1 during the time intervalpreceding the time intervalreset the specified group last (m=(imax-1)Q+1, (imax-1)Q+2,... ,mmax) discharged from the first movable object 1 intermediate transceiver stations 5, and transmit them. Similarly carry out reception and transmission of radio signals with the help of other groups (i=imax-2,imax-3,... ,1) discharged from the first movable object 1 intermediate transceiver stations 5 direction is to improve the transmission of radio signals from the reset intermediate transceiver stations 5 during the later time intervals to reset during earlier intervals

Take transmitted from each of the groups of the first (m=1,2,... ,Q) is reset with the first movable object 1 intermediate transceiver stations 5 radio signals on each of the first group (n=1,2,... ,Q) discharged from the second movable object 2 intermediate transceiver stations 5 and pass them. Take transmitted from each of the first group (n=1,2,... ,Q) discharged from the second movable object 2 intermediate transceiver stations 5 radio signals on each of the other group (n=Q+1,Q+2,... ,2Q) intermediate transceiver stations 5 discharged from the second movable object 2 during the time intervalfollowing the time intervalreset from the second movable object 2 of the first group (n=1,2,... ,Q) intermediate transceiver stations 5, and transmit them. Similarly carry out reception and transmission of radio signals using other (j=3,4,... ,jmaxgroup dropped from the second movable object 2 intermediate transceiver stations 5 in the direction of transmission of the radio signals from the reset intermediate transceiver stations 5 for earlier time intervalsto reset during the later intervals of time the Yeni .

Take the second movable object 2, the radio signal transmitted from each of the last group (n=(jmax-1)Q+1, (jmax-1)Q+2,... ,nmax) discharged from the second movable object 2 intermediate transceiver stations 5.

If in accordance with condition (38 in) reset intermediate transceiver stations 5 is carried out only with the first movable object 1, the radio transmission from the first mobile object 1 by using the reset with the first movable object 1 intermediate transceiver stations 5 is similar to the above case (38 g), and receiving transmitted from each of the groups of the firstflushed with the first movable object 1 intermediate transceiver stations 5 radio signals carry on the second movable object 2.

If in accordance with condition (38 b) reset the intermediate transceiver stations 5 is carried out only from the second movable object 2, the transmission radio signal with the first dropped from the second movable object 2 intermediate transceiver station 5 using the reset from the second movable object 2 intermediate transceiver stations 5 is similar to the above case (38 g), and receiving transmitted from the first mobile object 1 signals is carried out on each of the groups is ervah discharged from the second movable object 2 intermediate transceiver stations 5.

Each intermediate transceiver station 5 starts to operate at the time of reset and continues to function before and after contact with the underlying surface.

At lower intermediate transceiver stations 5 of their range and the range of radio broadcast stations 3 are reduced, but in accordance with the formulas (19)-(30) not be less than the value of RQ min.

The mutual displacement of the first movable object 1, the second movable object 2 and discharged from the intermediate transceiver stations 5 occurs Doppler effect, the negative impact on the communication quality can be resolved by rational choice of the frequency characteristics of signals and devices transmitting station 3, a receiving station 4 and the intermediate transceiver stations 5.

When implementing the method in rough terrain to determine discharge points intermediate transceiver stations 5, you must take into account the information about the height field terrain. For this purpose, the movable object 2 can be used in the review and comparative systems of navigation (see Aeronautical radionavigation: a Handbook. Edited Ass. - M.: Transport, 1990, p.8-9).

Podsta the surrounding surface may be the surface of the water. In this case, when implementing the method, you must keep the intermediate transceiver stations 5 on the surface of the water after a fall. In addition, when specifying ranges of validity transmitting station 3 and the intermediate transceiver stations 5, consider the excitement of the water surface and possible flow.

To reduce the amount of geometric space occupied by the communication system, and consequently, to improve the efficiency of the method in the simultaneous operation of multiple radio communication systems necessary for the completion of the radio communication between the first mobile object 1 and the second mobile object 2 to destroy discharged from the first movable object 1 and the second movable object 2 intermediate transceiver station 5.

The destruction of the dropped intermediate transceiver stations 5 can significantly reduce the amount of each of them, because the result of the destruction of the small and incapable of functioning parts of structures intermediate transceiver stations 5 can be stacked more densely.

The term “operating frequency” understand the value of carrier frequency oscillations, Central or any other characteristic frequency band of radio signals. When this band of frequencies of the radio signals, suitable for the e different operating frequencies, do not overlap.

For an arbitrary routes of movement of the first movable object 1 and the second movable object 2 set the operating frequencies of the radio signals transmitted at the same time with the first movable object 1 and each of the intermediate transceiver stations 5 discharged from the first movable object 1 and the second movable object 2 must be different:

When the radio transmission from the first mobile object 1 on the second movable object 2 specified operating frequenciesradio signals received at each of the intermediate transceiver stations 5 of the i-th reset with the first movable object 1 groups, except the last one (i=imax) group dropped from the first movable object 1 intermediate transceiver stations 5 are specified operating frequenciesradio signals transmitted from the intermediate transceiver stations 5 (i+1)-th group, dropped from the first movable object 1 in the next to the time intervalreset this (i-th) group later time interval:

at tata min; i≠ imax,

where q=1,2,... ,Q be positive integers

p> The specified operating frequency of the radio signals received at each of the intermediate transceiver stations 5 last (i=imax) discharged from the first mobile object 1 is specified operating frequency faradio signals transmitted from the first mobile object 1:

Specified operating frequenciesradio signals received at each of the intermediate transceiver stations 5 j discharged from the second movable object 2 groups, except for the first (j=1) group dropped from the second movable object 2 intermediate transceiver stations 5 are specified operating frequenciesradio signals transmitted from the intermediate transceiver stations 5 (j-1)-th group, dropped from the second movable object 2 in the next to the time intervalreset this (j) group earlier time interval

Specified operating frequenciesradio signals received at each of the intermediate transceiver stations 5 first (j=1) discharged from the second movable object 2 groups are specified operating frequenciesradio signals, lane is provided with an intermediate transceiver stations 5 first (i=1) discharged from the first movable object 1 groups, if the first mobile object 1 is reset at least one intermediate transceiver station 5, or, otherwise, the specified operating frequency faradio signals transmitted from the first mobile object 1:

Specified operating frequenciesradio signals received on the second movable object 2, are specified operating frequenciesradio signals transmitted from the intermediate transceiver stations 5 last (j=jmax) discharged from the second movable object 2 groups, if the second movable object 2 is reset at least one intermediate transceiver station 5, or specified operating frequenciesradio signals transmitted from the intermediate transceiver stations 5 first (i=1) discharged from the first mobile object group 1, if the intermediate transceiver station 5 reset only from the first mobile object 1, or given operating frequency faradio signals transmitted from the first mobile object 1, if no the first movable object 1 or the second movable object 2 is not reset any intermediate transceiver station 5 (the characteristic inherent in the prototype, and therefore it is included in the General part of the claimed formula izobreteny is):

From the above it follows that the operating frequencies of the radio signals received at the intermediate transceiver stations 5 and transmitted with them can be fixed.

In this case, when the discharge from the first movable object 1 intermediate transceiver stations 5 another group (i=imax) set the operating frequency faradio signals transmitted from the first mobile object 1 must match one of the specified operating frequencyradio signals received at the intermediate transceiver stations 5 given (i=imax) group. Before discharge from the first movable object 1 first (m=1) intermediate transceiver station 5 desired operating frequency faradio signals transmitted from the first mobile object 1 must match one of the specified operating frequencyradio signals received by discharged from the second movable object 2 intermediate transceiver stations 5 first (j=1) group.

However, when the discharge from the second movable object 2 intermediate transceiver stations 5 next (j=jmax) group specified operating frequenciesradio signals received on the second movable object 2 must match with specified operating frequency and radio signals transmitted from the intermediate transceiver stations 5 of this (j=jmax) group. Before discharge from the second movable object 2 of the first (n=1) intermediate transceiver station 5 specified operating frequenciesradio signals received on the second movable object 2 must match with specified operating frequenciesradio signals transmitted from discharged from the first movable object 1 intermediate transceiver stations 5 first (i=1) group.

In addition, for the implementation of the radio communication between the first mobile object 1 and the second mobile object 2 in the situation of (38), in which they have not dropped a single intermediate transceiver station 5, the specified operating frequency faradio signals transmitted from the first mobile object 1 must match one of the specified operating frequencyradio signals received on the second movable object 2.

All items and blocks included in the system represented in figure 1-7 are known and described in literature.

As each of the first measures 42 power and second gauges 58 power can be used connected in series block squaring and integrator (see, for example, Gandal, Aperol. Applied analysis of random data. - M.: Mir, 1983, p.143).

<> The first block 9 is reset and the second block 13 reset are designed to perform reset intermediate transceiver stations 5 with a specified interval in range.

As the first conveyor 15 and the second conveyor 19 used belt conveyors with horizontal closed track (see, for example, the Conveyors. The Handbook. Under the General editorship Uairen. - L.: engineering, 1984, p.4-9).

The first conveyor 15 is designed to move the intermediate transceiver stations 5, placed in the first bearing elements 17, in the direction of the first hole 26. The second conveyor 19 is designed to move the intermediate transceiver stations 5, placed second bearing elements 21, in the direction of the second hole 28.

The first actuator 14 and the second actuator 18 is intended for the propulsion of the first tape 16 of the first conveyor 15 and second tape 20 of the second conveyor 19 with speeds corresponding to the signals generated by the first control unit 8 and the second control block 10, respectively.

The first actuator 14 and the second actuator 18 are automated. Systems of automated control of electric drives provide a given angular velocity of the shaft of the motor in accordance with external control signals, which depending the type of motor and control system can be analog or digital (see, for example, Polytechnical dictionary. The editorial Board.: Awesomse (editor-in-chief) and others - 3rd ed., Rev. and supplementary): P “Great Russian encyclopedia”, 1998, s). The design of the actuator is known (see, for example, the Conveyors. The Handbook. Under the General editorship Uairen. - L.: engineering, 1984, p.87-91).

The power of the signals generated by the first control unit 8 and the second control block 10, is sufficient to control the operation of the first actuator 14 and the second actuator 18.

Construction of the first unit 9 reset provides unrestricted movement of the intermediate transceiver stations 5 to the first hole 26 when they are reset. Construction of the second unit 13 reset provides unrestricted movement of the intermediate transceiver stations 5 second hole 28 when they are flushed.

The dimensions of the first hole 26 exceeds the dimensions of each of the intermediate transceiver station 5. The dimensions of the second openings 28 exceed the dimensions of each intermediate transceiver station 5 in conjunction with the attached stowed parachute 23.

Enshrined in the first bearing elements 17 and second bearing elements 21, the magnets 24 is a plate made of hard magnetic materials.

Intermediate transceiver station 5 is placed in the first bearing elements 17 and second bearing elements 21 in the immediate vicinity of the magnets 24, the magnetic field which provides the closure of the contacts of the switches 68, however, is negligible in its impact on the movement of the intermediate proimperialist 5 when they are flushed.

The first transmitting antenna 33, the first receiving antenna 34, the second receiving antenna 50 and the second transmitting antenna 66 are non-directional.

Construction of the intermediate transceiver stations 5 will be developed with consideration of impact loads that occur when confronted with the underlying surface (see, for example, Webcamporn. Vibration and shock in radio. - M.: Soviet radio, 1971, s-216). In this regard, the second receiving antenna 50 and the second transmitting antenna 66 intermediate transceiver stations 5 can be placed inside the high impact of the radio waves buildings, made for example of PTFE.

Parachutes 23 serve to reduce the speed of falling intermediate transceiver stations 5 and, consequently, to reduce the shock loads that occur when they collide with the underlying surface.

The parachutes 23 second bearing elements 21 eliminates the tangling of slings 22 resetting the intermediate transceiver stations 5.

The physical and geometric characteristics of parachutes 23 (permeability, elasticity fabric dome, the shape and size of the dome, the presence and shape of the cutouts and other) is determined based on the weight of the intermediate transceiver stations 5 and the required dynamics of parachutes 23 (see, for example, Wasiljev, Vnesheco, Whatamango. Dynamics of parachute systems. - Kyiv; the Ode to the sa: “high school”. Head publishing house, 1985). Design and characteristics of parachutes 23 assume their automatic disclosure of resetting the intermediate transceiver stations 5.

Source 29 messages can serve as a device to sequentially output the digital signals, and the receiver 47 communications device serial input digital signals (see, for example, Digital and analog integrated circuits. The Handbook. Edited Svechenovskoj. - M.: Radio and communication, 1990, s).

Each of the battery 69 is designed to generate a voltage corresponding to the intermediate transceiver station 5. The capacity of the battery 69 set based on the power consumption of the corresponding intermediate transceiver station 5 and the duration of the operation.

The frequency and transmission of radio transmitting station 3 and the intermediate transceiver stations 5 are specified operating frequencies of the radio signals, transmitted respectively from the transmitting station 3 and the intermediate transceiver stations 5.

The frequency of reception of radio receiving station 4 and the intermediate transceiver stations 5 are specified operating frequencies of the radio signals received respectively at the receiving station 4 and the intermediate transceiver stations 5.

The terms “transmission frequency” and “frequency of use” of any device are generally accepted (see, for example, Gromakov Y.A. Standards and mobile radio systems. ): Eco-Trends, 2000, s).

The term “controlled oscillator is generally accepted (see, for example, theoretical foundations of radar. Edited Vaitulevich. - M.: Soviet radio, 1978, s). The oscillation frequency generated by the controlled oscillator is determined by the voltage acting on its control input. In this case, the controllable oscillator is controlled oscillator voltage. Generators driven by voltage, are known and described in the literature devices (see, for example, Horowitz P., hill. U. Art circuitry. In 3 volumes: T.1. TRANS. from English. - 4th ed. revised and enlarged extra - M.: Mir, 1993, s).

Consider the implementation of the method using the system presented in figure 1-7.

The first moving object 1 and the second movable object 2 are in common initial point O.

The gain of the first amplifier 32 and second power amplifiers 65 power is set so that the power of radio signals transmitted from the first mobile object 1 and the intermediate transceiver stations 5, was equal to R[Izl].

Then taking into account expressions (19)-(30) the range of radio broadcast stations 3 and intermediate transceiver stations 5 is equal to RQ mi .

In the first block 6 of the task and the second block 12 jobs enter values in the ranges RQ minsteps intermediate transceiver stations 5.

The first control unit 8 reads the code from the outputs of the first block 6 jobs containing information about the specified values of the distances RQ minactions, and determines the formulas (31), (32) the value of da minand Δ dm.

The second control block 10 reads the code from the outputs of the second unit 12 job containing information about the specified values of the distances RQ minactions, and determines the formulas (31), (33) the value of db minand Δ dn.

Let us assume that the transmission frequency of the m-th intermediate transceiver station 5, located on the first movable object 1, and the n-th intermediate transceiver station 5, located on the second movable object 2, respectively

where Δ f is the offset frequency.

The first control unit 8 and the second control block 10 generates control signals for which the frequency of oscillations generated by the first controlled oscillator 31 and the second controlled oscillator 38, respectively take the values of faandmoreover , in accordance with the formula(43), (44):

where fb p- intermediate frequency receiver station 4.

The contacts of the reed switch 68 of each of the intermediate transceiver stations 5, placed in the first bearing elements 17 and second bearing elements 21, are closed in the magnetic field of the magnet 24. The conclusions of the winding of an electromagnetic relay 67 is applied the voltage of the battery 69. The contacts of the electromagnetic relay 67 are opened. Transceiver unit 48 is de-energized. Intermediate transceiver station 5 does not function.

At timethe first movable object 1 starts to perform on the underlying surface of the common initial point O, located on the x-axis (figure 1), rectilinear motion with constant velocity Vaalong the x-axis in the direction of in the direction of decreasing values of X.

The first control unit 8 continuously reads the outputs of the first measuring device 7 speed with the speed of movement of the first movable object 1 and using the formula (34), (35) determines the points in time of the reset intermediate transceiver stations 5.

At timethe second movable object 2 starts to execute from a common start point Of the vertical height hb maxand then performs a horizontal flight at a height of hb max with constant velocity Vbalong the x-axis in the direction of in the direction of increasing values of X.

The second control block 10 is continuously reads the outputs of the second meter 11 speed with the speed of movement of the second movable object 2 and using formulas (36), (37) determines the points in time of the reset intermediate transceiver stations 5.

Let us assume that the acceleration of the first movable object 1 to a speed of Vaand the acceleration of the second movable object 2 to a speed of Vbwith the beginning of the horizontal movement is negligible. If the acceleration cannot be neglected, then the moments of time ta minand tb minreset the first intermediate stations 5 determined from the solutions of equations

At timethe first control unit 8 generates a control signal by which the first actuator 14 causes the first tape 16 of the first conveyor 15 movement speed:

The movement of the second belt 20 over the longitudinal axis of symmetry of the second conveyor 19 is in the direction of the second hole 28 (Fig 3).

The time during which the speed of the first belt 16 and second belt 20 reaches values Uaand Ubaccordingly, negligible.

Before time ta minfirst remove the first movable object 1 from a common initial point O, the distance da minand before time tb minfirst remove the second movable object 2 from a common initial point O, the distance db minno the first movable object 1 or the second movable object 2 reset intermediate transceiver stations 5 is not carried out (case 38, a).

In this case, the radio transmission from the first mobile object 1 on the second movable object 2 is as follows.

The binary sequence of pulses from the output of the source 29 message transmitting station 3, located on the first movable object 1, is fed to the first input of the first Converter 30 frequency. On its second input receives the oscillation frequency faproduced the first controlled oscillator 31. The value of frequency faask for the forms of the Le (49). Amplitude-shift keyed signal with the output of the first Converter 30 frequency is fed to the input of the first amplifier 32 power, the output of which is fed to the input of the first transmitting antenna 33. The first transmitting antenna 33 passes at a given operating frequency fathe corresponding signal.

The first receiving antenna 34 a receiving station 4, located on the second movable object 2 receives the radio signal transmitted by a radio transmitting station 3. The output signal from the first receiving antenna 34 is fed to the input of the first bandpass filter 35, which provides selectivity image channel (see, for example, a Receiving device. Edited Vietrova. - M.: Soviet radio, 1974, s). The output signal of the first bandpass filter 35 is fed to the input of the first low-noise amplifier 36, the output of which is fed to the first input of the second inverter 37 frequency. On its second input receives the oscillation frequencygenerated by the second controlled oscillator 38. The values of operating frequenciesthe received radio signals are defined by the formula (50). The signal of the intermediate frequency fb pfrom the output of the second inverter 37 frequency is fed to the input of the first amplifier 39 intermediate frequency, the output of which is fed to the inputs in the ex second bandpass filter 41. (The spectrum of the signal current at the output of the second inverter 37 frequency, contains components corresponding to operating frequencies of the received radio signals.
