The invention relate to ammunition and more particularly to engineering and mines directional and can be used in the systems of protection of critical facilities from air tools attacks (UAVs, cruise missiles, hang gliders, small aircraft) [1].

Known anti-aircraft missile systems designed to destroy air targets. The disadvantage of these technical means is the low efficiency in defeat low-flying targets [2].

The closest in technical essence is protivogololednoy Mina Temp-20" [3]. It is designed to hit targets high impact core at distances of up to 150 m This protivogololednoy mine using acoustic system detects an aerial target at ranges of up to 1 km, engages the side towards the goal and by scanning with optical multi-frequency passive infrared sensor, determines the true direction of the target and the time of detonation of the warhead.

The disadvantage of such tools is the inability to engage air targets with a low level of self-acoustic emission (UAV, aviation planning mode). Also hampered the detection of targets in adverse weather conditions (heavy snow, rain) - due to the large loss of IR radiation propagating from the target.

The technical result of izaberete the Oia is to increase the reliability of damage of small air targets in any weather.

The technical result is achieved in that the detection of a target engineering mine is using a bistatic radar sensor.

The use of bistatic sensor target, compared to conventional single-station, provides reliable detection of low-flying targets in any weather. This also significantly increases the reliability of detection of small targets in the construction of which is used malatrasi microwave electromagnetic field.

Radar transmitter bistatic radar system is located on the protected object. Autonomous Doppler radar receiver of this system is installed on environmental object location together with a fragmentation warhead.

Reflected from the aerial target probing radar signal gets in the Autonomous radar receiver, which causes the electromagnetic warhead, shot sheaf ready ferromagnetic fragments towards this goal. Thus the detection zone of the radar receiver aligned in space with area of effect projectile fragmentation warhead.

To increase the stealth of work, the working carrier frequency bistatic radar sensor target is set equal to the carrier h is h satellite navigation system. This increases the reliability of operation under the influence of the REB.

Figure 1 shows a structural diagram of a device that implements the proposed method for the destruction of low-flying targets. The device defeat low-flying targets contains stationary radar transmitter (1), Autonomous Doppler radar receiver (2) and combat fragmentation part of the targeted lesion (3).

The device defeat low-flying targets is as follows. Probing radar signal radiated by a transmitter (1)reflected from a low-flying target (4), is taken offline Doppler radar receiver (2). With its output control signal causes actuation of the electromagnetic warhead (3), shot ready ferromagnetic debris in the direction of the target (4) which impress her.

SUBSTANCE: method of phasing radio signals emitted from spaced-apart points of a moving object, with action of said signals on radar stations with target selection according to speed, can be used in a radar station. The method is realised by generating, at each of said points of the object, paired signals and successively emitting said signals; frequency shifting between signals in a pair is carried out equal to the first intermediate frequency of the receiver of the radar station; when relaying a radio signal received from the radar station, frequency shift of each pair is carried out by the same value with separate selection of upper side and lower side frequencies, thereby introducing a direct detection mode into the radar station and maintain coherence and phase opposition of the signals; the dephasing action of the reflected signal is prevented by frequency deviation and overlapping the received oscillation with narrow-band noise.

SUBSTANCE: initially formed standard information array of signals of initial alignment of inertial direction finding of a given viewing object and measured signals that are proportional current values of projections of the vector of apparent linear acceleration and projections of the vector of the absolute angular velocity of the viewing vector of the viewing object on corresponding axes of the base antenna coordinate system are used to generate signals that are proportional to current values of parameters of inertial direction finding of the given viewing object, that are characterised by the current value of mismatch between the initial value of inclined range to the given viewing object and the current value of inclined range of approaching the given viewing object of the base of an integrated antenna device together with a mobile carrier, i.e. components of the error between the direction of the viewing vector from the given viewing object in two mutually perpendicular planes of its direction finding in the base antenna coordinate system. During radar automatic tracking of the viewing object based on the received signals reflected from the viewing object irradiated with probing microwave signals, signals for radar direction finding of the viewing object in two mutually perpendicular planes of its direction finding in the base antenna coordinate system are simultaneously generated. Signals for radar direction finding of the viewing object respectively characterise current values of mismatch, i.e. components of the error between the direction of the optical axis of the mirror of the integrated antenna device and the current value of the direction of the maximum of the beam pattern of the integrated antenna device when emitting probing microwave signals towards the viewing object. The generated signals for radar and inertial direction finding are respectively corrected and compared, and a difference signal, which is subjected to low-pass filtering, is generated and subjected to adaptive noise-immune statistical estimation. Broadband noise of radar direction finding of the viewing object is suppressed; difference signal estimation narrowband noise is selected; a signal which is proportional to the accurate estimation of the difference signal is then generated to compensate for the narrowband noise caused by an error in inertial direction finding of the viewing object. To this end, the signal which is proportional to the accurate estimate is summed with the signal of inertial direction finding of the viewing object, resulting in compensation for narrowband noise, i.e. the error, resulting in generation of a filtered signal for controlling the direction to the viewing object of the viewing line, which is generated with minimal error. The signal which is proportional to the minimal error is defined as the difference between a signal which is proportional to the equivalent measurement error of the angular coordinate of the viewing object and a signal which is proportional to compensation of the accurate estimate of the difference signal. The signal which is proportional to the equivalent measurement error of the angular coordinate of the viewing object is proportional to the difference of angular displacement caused by free movement and narrowband noise, i.e. the error in direction finding of the viewing object. The method is realised by the disclosed integrated complex system, which consists an inertial automatic tracking loop which includes an inertial angular discriminator of signals of direction finding of the viewing object in two mutually perpendicular planes of its direction finding in a base antenna coordinate system and a fourth adder, a radar automatic tracking loop which includes a radar angular discriminator for direction finding of the viewing object in two mutually perpendicular planes of its direction finding in a base antenna coordinate system, a first adder, a second adder, a first correcting circuit, a filtering and compensation loop which contains a second correcting circuit, a second comparing element, a low-pass filter, a third adder, a filtering and compensation loop which contains a second correcting circuit, a second comparing element, a low-pass filter, a third adder, a gyrostabilisation and control loop which contains a dynamic unit encircled by a direct negative feedback. The system also contains a first comparing element, a switch for switching operating modes of the system, an information line for linking the inertial angular discriminator with external equipment for preparing and controlling launch of the mobile carrier, an information line for linking the inertial angular discriminator with the integrated antenna device. The system also includes integrated antenna devices, an antenna-waveguide and receive-transmit unit and a digital computer. The integrated antenna device contains a mirror with a radiator, capable of turning in two mutually perpendicular planes relative to the radiator, having a double-axis gimbal suspension rigidly mounted on the base of the integrated device and pivotally connected to the mirror, carrying in an internal frame, appropriately mounted gyroinertial sensors of signals of spatial movement of the mirror, sensors of signals of the rotation of the outer and inner frames of the double-axis gimbal suspension, electronic units for gyrostabilisation and controlling the direction of the mirror towards the viewing object, an amplifier for feedback signals in corresponding channels of a two-channel gyroscopic sensor of angular velocity signals, electronic units for generating control signals proportional to the given angular velocity of the rotation of the mirror in the horizontal plane and the vertical plane, respectively, an electronic unit for scaling the signal obtained at the output of the electronic unit for generating a control signal of the given angular velocity of the rotation of the mirror in the vertical plane, proportional to the projection of the vector of absolute angular velocity of rotation of the mirror on the transverse axis of the axis of the coordinate system associated with the mirror. The antenna-waveguide and receive-transmit unit, which is connected to a radiator, contains appropriately connected sum-difference converter of microwave signals, waveguide-switching device, transceiver, connected by an information line to the corresponding output digital computer, through which the unit interacts with the digital computer.

SUBSTANCE: in order to use coherent accumulation when detecting parametric scatterers, a pair of short successive auxiliary radio pulses with identical shape and opposite phases is emitted simultaneously with pumping radio pulses at the sub-harmonic frequency of the pumping radio pulses. One of the radio pulses of the pair is a synchronising radio pulse and for this purpose, said pulse must be emitted in such a way that a pumping radio pulse is emitted over its duration. However, if during parametric excitation of the response signal in the parametric scatterer the phase of the synchronising signal differs by π/2 from the phase of possible signals that can result from parametric generation, synchronisation will not take place. In order to avoid missing a target as a result of this phenomenon, emission of a sequence of radio pulses of the pumping signal in series that differ on phase by π is proposed. If for one series of radio pulses of the pumping signal conditions are created where there will be no synchronisation, then for the next series synchronisation will definitely take place and coherent accumulation of the response signal in the receiver will be possible.

EFFECT: avoiding missing a target due to lack of synchronisation.
