Description

The proposed technical solution relates to the field of defense technology, in particular to mobile anti-aircraft missile systems (SAM), and can be used to organize air defense of troops and military installations from defeating enemy air attack weapons.

In the structure of modern air defense (air defense), a radar station (RLS) is the main and almost the only source of information about the air situation of air attack equipment (STS), and the tactical order of modern aviation, together with ballistic missiles and cruise missiles designed to break through air defense, necessarily provides fire suppression of anti-aircraft defense, since the radar provides control of the area of responsibility of anti-aircraft defense and the issuance of target designation to active-targeting radar systems - ZR and fighter aircraft.

A known SAM (see Soldat und Technik, 1987, No. 4, p.262), containing three modules, each of which is placed on a separate trailer, a three-coordinate radar for viewing, detecting and tracking targets, as well as an anti-aircraft missile control system (SAM) ) a two-beam radar for target and missile tracking, a firing unit with missiles and an electron-optical system for automatically tracking missiles and targets.

The presence of two parallel operating guidance systems allows the complex to simultaneously direct two missiles, however, placement on three trailers requires a large deployment time of the complex, which increases the reaction time and reduces the effect of its use.

Known self-propelled anti-aircraft missile system (SAM) "Cube" (see Equipment and weapons, 1999, No. 5-6, p. 28-34), consisting of a self-propelled launcher with missiles, a self-propelled installation of reconnaissance and guidance, containing a radar station (Radar) detection of air targets and target designation and radar tracking of targets and lights, means of target recognition, navigation, topographic and orientation (SNTO) system, radio telecode communication system with launcher, television optical sight (TOV), autonomous power supply, elevation system en enny and leveling. The complex is single-purpose and is located on several tracked vehicles.

A mobile combat installation is known that is equipped with a multi-barrel missile launcher (see DE patent No. 2356462, IPC F41G 07/00, 1976), comprising a radar, guidance and target designation system, computing and control equipment, search antennas, tracking and transmitting control commands to the missile as well as a television camera, a laser rangefinder and an infrared target tracking system.

Known self-propelled combat vehicle short-range air defense systems (see patent RU No. 2121645, IPC F41H 07/00, 1998), comprising a self-propelled chassis with a cabin, an antenna-launching device rotating on a support bearing, consisting of a guidance system with an antenna, a target detection system with antenna and a starting device, in addition, the machine contains a shaft located in the antenna starting device.

The specified technical solution provides a small range of destruction of the air enemy.

Known SAM with PRGS SAM "HOCK" (see Wehrtechnik, 1977, No. 1-2), containing a radar for detecting air targets, a fire control system, radar tracking and illumination and SAM with PRGS.

Known SAM "Krotal" (see Foreign Military Review, 1999, No. 10, p.2-5), containing radar detection, launcher with a vertical launch missiles.

A VT-1 missile is used for cold start, a feature of which is firing a rocket using a powder pressure accumulator at a speed of 40 m / s, driven by a gas generator, then the main engine is launched, and the rocket is rotated using a separate rotary module controlled by an onboard by computer.

Famous SAM "Patriot", located on several wheeled chassis (see Equipment and armament, 1992, No. 9-10, pages 38-39, V.V. Malikov, SAM "Patriot"), containing a multi-function radar with headlight, group antennas for suppressing side lobes, a transmitter unit, a receiver unit, a digital signal processing system, a digital control and synchronization computer system (DAC), a friend-or-foe identification system, equipment for generating and transmitting control commands on board a missile in radio reaction conditions, a gas turbine generator for power supply, p ost controls, communications, diagnostic system for monitoring the state of the elements of the complex.

The complex requires a lot of deployment time.

The above analogues have one or another of the following main disadvantages:

- Separate deployment of radar for detection, tracking, illumination of targets for guiding missiles and a launcher with missiles on several SAM systems;

- a significant deterioration in the tactical and technical characteristics of air defense systems in a complex jamming environment.

The closest in technical essence and the achieved result is self-propelled firing mount (SOU) 9A310-M1 SAM "BUK-M1" GS1.641.006 TO (see Military Parade, 1997, No. 1, pp. 28-32, V.V. Matyashev , SAM "BUK-M1"; Equipment and armament, 1999, No. 5-6, pp. 35-41), containing radar for the detection, tracking and illumination of targets in the C-band, as well as a rotary launcher with missiles, and the radar station located on a self-propelled launcher and consists of an electromechanical antenna, a transceiver system, a digital control computer system synchronization, a synthesizer for generating letter frequency signals, a friend-or-foe recognition system, equipment for generating and transmitting radio correction (control) commands on board a rocket, in addition, roll and pitch angle sensors and a navigation system are located on the launcher, Topographic reference and orientation (SAT), telecode communication system and operational-command communication.

The disadvantage of this technical solution is a significant deterioration in the tactical and technical characteristics of the JMA in a complex jamming environment.

The technical result of the proposed solution is the creation of a self-propelled fire installation for detecting, tracking, guiding and launching missiles of an anti-aircraft missile system of medium range, which ensures effective combat operation in difficult interference conditions.

The technical result is achieved by the fact that a self-propelled firing installation for detecting, tracking and illuminating targets, guiding and launching missiles of an anti-aircraft missile system of medium range, contains a first antenna system, the output of which is connected to the first input of the radar station, the first output of which is connected to the first input of the digital computer system . The first output of the digital computing system is connected to a rotary launcher with missiles, on which a gyroscopic system for measuring heading angles, roll and pitch is installed, the input of which is connected to the output of a navigation, topographic and orientation system located on a self-propelled chassis. The output of the gyroscopic system for measuring heading angles, roll and pitch is connected to the second input of the digital computer system, the second output of the digital computer system is connected to the second input of the radar station, the second output of which is connected to the input of the first antenna system.

New in the proposed technical solution is the introduction of a second antenna system, a receiving device and an intelligent system. The output of the second receiving antenna is connected to the input of the receiving device, the output of the receiving device is connected to the first input of the smart system, the output of the smart system is connected to the third input of the digital computer system, the third output of which is connected to the second input of the smart system.

Figure 1 shows a structural diagram of a self-propelled fire installation for detecting, tracking and illuminating targets, guiding and launching missiles of a medium-range anti-aircraft missile system.

Figure 2 presents a functional diagram of a self-propelled fire installation for detecting, tracking and illuminating targets, guiding and launching missiles of an anti-aircraft missile system of medium range.

Self-propelled firing installation for detecting, tracking and illuminating targets, guiding and launching missiles of an intermediate-range anti-aircraft missile system (SOU), contains the first antenna system 1, radar station 2, digital computer system (CVS) 3, and a rotary launcher with missiles (PU) 4 moreover, on a rotary launcher with missiles 4 there is a gyroscopic system for measuring heading, roll and pitch (GS) 6 angles, necessary to stabilize the beam of the first antenna system 1, the second antenna system 7. On a self-propelled chassis azmescheny navigation system, topographic location and orientation (SNTO) 5, the receiving apparatus 8 and 9, the intelligent system.

The output of the first antenna system 1 is connected to the first input of the radar station 2, the first output of which is connected to the first input of the digital computer system 3. The first output of the digital computer system 3 is connected to a rotary launcher with missiles 4, on which a gyroscopic system for measuring heading angles and pitch 6, the input of which is connected to the output of the navigation, topographic and orientation system 5, located on the self-propelled chassis. The output of the gyroscopic system for measuring heading angles, roll and pitch 6 is connected to the second input of the digital computer system 3, the second output of the digital computer system 3 is connected to the second input of the radar station 2, the second output of which is connected to the input of the first antenna system 1. The output of the second receiving antenna 7 connected to the input of the receiving device 8, the output of the receiving devices 8 is connected to the first input of the intelligent system 9, the output of the intelligent system 9 is connected to the third input of the digital computing system s 3, wherein the third output is connected to the second input of the intelligent system 9.

Self-propelled firing installation for detecting, tracking and highlighting targets, guiding and launching missiles of the medium-range anti-aircraft missile system (SOU) works as follows.

After setting the SDA to the combat position, from the navigation, topographic reference and orientation system 5 to the gyroscopic system for measuring heading angles, roll and pitch 6, TsVS 3, the value of the SDA heading angle (the angle between the longitudinal axis of the SDA and the north direction) is entered. The heading angle of the SDA is used in the gyroscopic system for measuring heading, roll and pitch 6 angles as initial conditions, and in the process of further work, the gyroscopic system for measuring heading, roll and pitch 6 angles gives the course value taking this angle into account. In CVS, the SDA course angle is used in correction sessions to calculate the angle ψ _calc , where ψ _calc is the calculated angle.

The signals from the output of the first antenna system 1 are issued to the input of the radar 2, which performs the detection, capture, tracking and illumination of targets.

After amplification and conversion, target signals are issued from the first output of the radar 2 to the first input of the DAC 3, in which the control signals of the launcher 4 are generated to generate lead angles and the formation of missile guidance signals. The generated signals are issued from the first output of the DAC 3 to the input of the PU 4.

A gyroscopic system for measuring heading angles, roll and pitch 6 is installed on the control unit 4, which is necessary to stabilize the beam of the first antenna system 1 in space when turning the control unit 4 in the horizontal plane and in the presence of rolls. Measured values of the course angles gyroscopic rate output angle measurement system, pitch and roll angular coordinate ψ 6 _edited fed to the second input of DDS 3, where _MOD ψ - measured in the horizontal plane heading angle SDA.

After averaging, the difference Δ = ψ _ism -ψ _{calculation is calculated} , which is used in the DAC to stabilize the beam of the first antenna system 1.

In difficult jamming environments, the following are used: a second antenna system 7, a receiver 8 and an intelligent system 9.

It is known (see Perunov Yu.M., Fomichev K.I., Yudin L.M. Radio-electronic suppression of information channels of weapon control systems M .: "Radio Engineering", 2003. - pp. 26-29) that the basis of methods of radio-electronic suppression (REP) Radar SOU constitute active and passive interference, aimed at creating a masking or misinforming effect. In addition to them, the main REP methods include methods of power energy suppression designed to disable certain elements of receiving devices, methods of environmental impact, in which radio signals of suppressed radars are distributed, distortion of the shape of the sounding and reflected signals about the object, weakening the power of sounding and reflected signals ; methods to reduce the effective scattering area (EPR) of targets.

Active interference is generated by interference transmitters. By the effect of action, they are divided into masking and imitation. Active masking interference includes noise and chaotic impulse noise. Active imitation interference is usually intended to misinform and create false information in processing systems.

The formation of active interference can be carried out in the following ways: generator; relay; relay-generating.

The second antenna system 7 detects interference, the receiving device amplifies, filters and matches the receiving device 8 with the intelligent system 9 (IC), the IC analyzes the useful signal coming from the DAC and the interference, recognizes the interference class, decides on the optimal, according to the criterion of maximum ratio signal / interference, a method or method of compensating for the effects of interference of this class, generates and issues a command to turn on the selected optimal mode of operation of the radar on the DAC.

Two requirements are imposed on the second antenna system 7: the viewing sector in azimuth is about 300 degrees (60 degrees shielded by missiles on the launcher), in elevation about 60 degrees, the possibility of direction finding to the source of interference with an accuracy of 5-10 degrees. The technical implementation of such an antenna system does not cause difficulties, for example, several horn antennas or a slot antenna with mechanical rotation in azimuth, the ways of constructing the antenna system are described in the literature (see Drabkin A.L., Zuzenko V.L., Kislov A.G. Antenno - feeder devices. - 2nd ed., revised and additional - M. Sov. radio, 1974, Antennas and microwave devices. Calculation and design of antenna arrays and their radiating elements. / Edited by DI Voskresensky. M .: Soviet radio, 1972, etc.).

The receiving device 8 is a multi-channel receiver, the implementation options of which are discussed in detail in the literature (see Tsarkov N.M. Multichannel radar meters. - M .: Sov. Radio, 1980., Radio receivers. / Ed. By A.P. Zhukovsky , - Higher School, 1989., Red E.T. Circuitry of radio receivers. - M .: Mir, 1989 and others).

An intelligent system can be implemented in the form of an expert system or a neural network (see Gaskarov D.V. Intelligent Information Systems. - M.: Higher School., 2003., Popov E.V. Expert Systems. - M.: Science, 1987., Callan Robert, Basic Concepts of Neural Networks, Translated from English - M .: Publishing House "Williams", 2001., Neural Networks. STATISTICA Neural Networks: Translated from English - M: Hotline - Telecom. 2001. and others). The training of the intellectual system is carried out according to the methods developed at present (see Berestova V.I., Rybina G.V. Technology for designing knowledge-based systems based on the INTER-EXPERT and LEONARDO tools: Laboratory workshop. - M.: MEPhI , 1992, Rybina G.V. Design of knowledge-based systems.- M.: MEPhI, 2004; Osipov G.S. Acquisition of knowledge by intelligent systems.M .: Nauka, 1997, Gavrilova T.A., Khoroshevsky V.F. . Knowledge Base of Intelligent Systems. - St. Petersburg: Peter, 2000 and others.).

IP training is carried out using well-known methods and methods of countering interference in radar (see Yudin L.M., Fomichev K.I. Radio-electronic countermeasure systems. Storing high-frequency signals. - Electronics, NTB, 1999, Vakin S.A., Shustov L. .N. Fundamentals of electronic warfare.VVIA named after Prof. N.E. Zhukovsky, 1998, Paly A.I. Electronic warfare. - M.: Military Publishing, 1981, Vakin S.A., Shustov L.N. Fundamentals of radio countermeasures and of electronic intelligence. - M .: Sov. radio, 1968., Tuzov GI. Immunity of radio systems with complex signals. Ami. - M.: Radio and communications, 1985, Protection against radio interference. / Under the editorship of MV Maksimov. - M .: Soviet radio. 1976, Gutkin LS. The theory of optimal methods of radio reception in case of fluctuation interference. - M .: Sov.radio, 1972, etc.) the algorithms of various methods and methods of protection against various classes of interference are stored in the DAC and are switched on by a command from the IC.

Thus, the proposed self-propelled firing installation for detecting, tracking and illuminating targets, guiding and launching missiles of an anti-aircraft missile system of medium range can provide effective combat work in a difficult jamming environment without compromising the main tactical and technical characteristics of the SDA.
