The invention relates to methods of preventing penetration of enemy reconnaissance and attack by air wire fences and can be used in peacetime to prevent terrorist unauthorized intrusions, unmanned aerial vehicles (UAV) controlled territory (the territory of the state across the border) in order to conduct reconnaissance or combat operations when making the enemy reconnaissance flights and attacks on objects using BLAH.

There is a way to counter the tasks UAV held anti-aircraft complex, consisting of radar air surveillance in the detection of UAV radar detection, in the capture of BLAH on automatic tracking in elevation s and the azimuth of P, and possibly on the distance R station maintenance purposes, the choice of mode shooting complex UAV (gun or missile), in the transmission of the coordinates of the UAV and other data from the station discovery and station maintenance at the Central computing system for solving the problem of fire control in accordance with the selected mode of firing, opening fire on BLAH and his defeat by the fragments of a missile or SN the rows, in assessing the results of shooting to determine the need for re-shelling BLAH or transfer of fire to another target [1]. In the list of tasks of modern anti-aircraft gun and missile system "Tunguska-M [1] States that it is designed for air defense of the objects from the shock tactical and army aviation, fire support helicopters, unmanned aerial vehicles, etc. the destruction of the UAV is included in this list not only of a single anti-aircraft gun and missile system, but also in the number of combat missions vast majority of anti-aircraft complexes and systems of the Russian Federation [2-7].

The disadvantage of this method is [8]:

1) low probability of detection BLAH station detection complex, especially when using mini-UAVS and micro-UAVS with the dimensions of less than one meter;

2) significantly reduced (in comparison with other typical air defense systems air targets) probability of damage, even deep in the affected area at short range, because this probability depends essentially on the geometrical dimensions of the target;

3) the relatively high cost of implementation, as the cost of military equipment Zenith complex is much higher than the cost of UAVS, which may be duplicated in several other similar BLAH, and after taking a UAV to support the giving of the complex reveals his location and can become the object of the attack other BLAH, anti-radar missiles, guided bombs, etc.

There is another way to counter the tasks unmanned aerial vehicle [9], namely, that with the help of high-precision detection system and aiming to discover performing their tasks BLAH pass in the tracking mode (aim) for BLAH by angular coordinates (or better over the angular coordinates ε, β and on the distance R), suggest the UAV combat laser beam apparatus of high power, located on the platform of an armored or similar tools, and keep the laser beam on the BLAH up until this UAV will not fail.

The disadvantage of this method is the requirement of very high accuracy of definition of coordinates of the UAV to output a laser beam at the point of its location, which is essentially probabilistic (false) event. The probability output of the laser to the point of BLAH in the process of constant movement UAV is greatly reduced in the presence of interference, reducing the light (if the detection system is optical), increasing the range of up to BLAH, the decrease in the height of its flight, and in the presence of precipitation laser radiation is highly absorbed by them and the damaging effect disappears.

Also known way to counter the tasks unmanned aerial vehicle called the way the functionality is a high destruction of electronic equipment BLAH [10], which includes object detection, recognition of the fact of belonging of the object to the class of UAV, the mode accurate tracking of UAV in hover over it with beam tracking stations (optical cross coordinator), irradiation BLAH powerful stream of microwave radiation at frequencies corresponding to the frequency range of avionics BLAH. There are other various options for implementation of a functional lesion of semiconductor electronic funds missiles, and UAVS powerful radiation [11].

The disadvantage of this method is the need to use expensive equipment to create a power of the order of units of tenths of GW. Another disadvantage is the need to hit the damaging radiation on expanding transceiver system blah BLAH, which is not always possible and depends on the position of the glider UAV relative to the emitter. The disadvantage is unintentional defeat all other electronic means, not related to the means of enemy intelligence, or BLAH-offender, and the impossibility of quick determination of the fact of what BLAH is really derived from the operation mode, depressed, his equipment is not able to provide the assigned tasks.

Also known way to counter the tasks unmanned Le is telnum apparatus [12], namely, that the unmanned aerial vehicle is detected by the radar or optical detection tool, and after a rough measure its coordinates, i.e. the elevation angle ε, azimuth β, the distance R and the height H in the area of its flight send a special unmanned aerial vehicles (or one unit) with equipment for jamming satellite or other channel navigation and orientation, which are constantly used in committing flights in the areas of unauthorized flights or in the border areas of unmanned aerial vehicles of the opposite side, have the equipment with equipment of jamming as close as possible to unmanned offender and always above its path (location), i.e. in a region of space that UAV uses for receiving navigation signals from the satellites, include approaching the jamming equipment and move jammers (i.e. their UAV) in the direction of the trajectory of unmanned offender as long as he does not go beyond the boundary of the controlled area or don't stop flying because of the crash, fall, or liquidation.

This way of countering this is the most efficient, but has the following the following disadvantages:

limited flight time and work and the equipment jamming;

the uselessness and harmfulness of the use of jammers in the areas of flight of their funds with satellite navigation;

the inability to prevent the departure of unmanned offender to the base of the dislocation with the received data;

the inability impacts (dissolution, termination of the flight) on drums BLAH, moving along a pre-planned trajectory to the target;

the difficulty saving mode pomerovpetrova in the navigational channel with good manoeuvring properties unmanned offender, i.e. the difficulty of continuous monitoring his movements.

The objective of the invention is to develop a new way of combating tasks unmanned aerial vehicle, characterized by long duration, relative cheapness, efficiency, adaptation to the altitude unmanned offender applicable, both in peace and in wartime, suitable for use as reconnaissance and shock BLAH.

For solving the problem of the invention it is proposed to use a system of N balloons 1 (see figure 1), fixed ropes at the points A1And2,...ANto the earth's surface. Balloons 1 are arranged in a time of war on the front line of defense of the territory occupied by friendly or his troops, and should cover the corridor Naib is more probable migration of enemy reconnaissance and percussion BLAH. In peacetime, the balloons come along borders with neighbouring countries, where expected unauthorized entry such blah BLAH.

Each balloon must have a container 3 with the apparatus in the middle of radar, optical, thermal detection 3, similar to that used on the UAV. The containers 3 are mounted on the bottom of the balloons (one for each balloon). Have balloons detection of optical and radar ranges will provide a better search aircraft in the area of responsibility or the area most likely spans BLAH (in the hallway expected intrusions, BLAH). Information about the detected air artificial objects comes wired (fiber optic cable) communication lines, attached to the cables 2, holding balloons 1, or by radio control at the point of information processing and management (POI) 5 (figure 1 communication lines shown by dashed lines).

Item information processing and management 5 unites and identifies information discovery from containers 3 different balloons 1 and transmits it to the General control means counter UAV. It is assumed that the proposed system counter is an element of a more global system, with a great many what obrazem detection and subsequent impact on BLAH. Such detection means may be, for example, a typical radar air defense or civil aviation. And how that impact can be attributed to the combination of adaptive interactive ways-analogues [1, 9-11], the prototype method [12], and the rise of aviation and the use of its on-Board firearms, artificial formation of strong gusts of wind, frost, rain, shock waves short range, using attacks specially trained birds of prey or aimed flights of large flocks of birds, knocking down everything in its way of flying vehicles, including unmanned and direction in the areas of UAV flights specially trained for gliders or paragliders with the task of destroying the UAV from small arms or trapping BLAH special means of capture (nets, nets, etc).

The ropes holding the balloon 2, fixed on the earth's surface in special containers 4 with gear-driven, POIU 5. Gearboxes should be able to increase or decrease the height of the balloons h, i.e. to wind or unwind the cables balloons on the control signals. The initial height of the balloon should be maximized to increase the range and quality detection UAV using detection equipment placed in con is anare 3. And then it can change to the scope of barriers to migration BLAH corresponded to the height of its flight, or to release air corridor for the migration of their aircraft.

The basic element of combat tasks BLAH is a system of wire, mounted on a rectangular frame, which is suspended under the balloon. Wire of education (obstacles) must be a so-called potency, widely used in ground engineering barriers to enemy infantry [13]. Wire potency should the height of the overlap region Y of the order of 10-20 meters (or even more), because the accuracy of determining the altitude UAVS are low, and in conditions of a priori uncertainty is generally unknown. In the absence of information about the altitude UAV altitude hold putnok should correspond to the most probable altitude UAV on the experience of their previous intrusions. Wire potency should be the most subtle of known variants. It is desirable to use smooth wire without chipping and needles, because this design has less weight and therefore requires smaller balloons. The degree of entanglement and intertwining of individual povolokin (hairs) in potence should be such that the mini-UAV couldn't besprepjatstvenno is to overcome the stretch potency in any place of its holding in the air.

The distance between cables 2 balloons d is selected considering the overlap of all politopnah from BLAH directions. The number N of balloons should be such that the entire corridor of migration BLAH or all border strip, within which is expected to breach the boundaries of UAV, were blocked. Ideally, the balloon barrier should be few, and the height of the rows of balloons must be different, so that together they overlap as much as possible high-altitude region. In this case, the system of containers 3 with means of detection should be used only in the outer (closest to the bases of the dislocation BLAH) number of balloons.

Variant of dvuhrazovoe wire fences with balloons depicted in figure 2. Potency 1 external number 6 have a height above the ground h1. Potency 2nd internal number 7 have a height above the ground h2. Lifting height putnok 2 in the second row must be equal to h2=h1+Y. the Distance along the horizon from 1 to 2 in the second row barrier should be such that, with a relatively straight flight UAV did not significantly change the height of its movement during the time span from the 1st row to the 2nd row of putnok. In this case, the total height of the barrier for UAVS increases from Y to 2Y.

Pets using option system balloons no means found is ugenia with a lifting height of wire, focused on the most probable altitude UAV on the experience of previous violations or unauthorized funds according to the review space other systems, departments, divisions. The number of balloons N provided is determined structurally by a distance (base) one pair d and the length S of the corridor overlap N=S/d.

The proposed system and method of counteracting have limitations associated with locations in the control area of forest belts, transmission lines and other tall objects preventing the initial lifting system with the earth's surface. However, below the tops of the trees of a forest UAV to fly, and the system can be placed in the depth of the zone of control on the extremities of the forest. In this case, the length of line overlap may increase. In the event of a shortfall in the number N of the balloon system, it is advisable to pull in the line, moved away from the unevenness of the end of the forest in the depth of the controlled area.

The method of combating tasks BLAH is that BLAH intruder always moves along the planned route, using or inertial navigation system orientation, and does not control the state of the air space on the way. Typically, BLAH is a lightweight device with a small the Yaga propulsion, as a result, getting into the area occupied by putankebi (tangled wire), BLAH cannot be overcome, becomes confused and loses control. The task BLAH exploration of objects, opening positions, putting weapons etc. is outstanding, which is the purpose of the proposed defenses. The next lowering of balloons 1 area of putnok on earth are examined, and all detainees BLAH retrieved for evidence of unauthorized violation of the limits or removal intelligence information.

Advantages of the method and system include the ability to use it in any weather conditions at any fractures of folds (e.g., mountainous areas), relative cheapness, the constancy of operation for a long time.
