Description

The invention relates to the field of aviation technology, and in particular to methods for protecting aircraft (LA) from air defense (Air Defense).

Air defense means, as a rule, include fighter-aircraft, anti-aircraft missile, anti-aircraft gun-missile systems (systems) and portable anti-aircraft missile systems.

Modern combat aircraft (LA) for protection against air-to-air guided missiles (UR), anti-aircraft missile systems (SAM) and man-portable air defense systems (MANPADS) are equipped with electronic countermeasure systems (CREP) and optical-electronic suppression systems (SOEP), such as "MiysisDIRCM" (published on the Internet at https://www.leonardo.com/en/press-release-detail/-/detail/idex-selex-es-introduces-miysis-dircm) , "President-S" (published on the Internet at https://topwar.ru/85537-bortovoy-kopleks-oborony-letatelnyh-apparatov-prezident-s.html), "Talisman" airborne defense complex ( published on the Internet at https://defin.by/products/talisman/), a set of electronic warfare equipment "Khibiny" (product L-175) (published on the Internet at https://ru.wikipedia.org /wiki/%D0%A5%D0%B8%D0%B 1%D0%B8%D0%BD%D1%8B_(%D0%BA%D0%BE%D0%BC%D0%BF%D0%BB% D0%B5%D0 %BA%D1%81_%D1%80%D0%B0%D0%B4%D0%B8%D0%BE%D1%8D%D0%BB%D0%B5%D0 %BA%D1% 82%D1%80%D0%BE%D0%BD%D0%BD%D0%BE%D0%B3%D0%BE_%D0%BF%D 1%80%D0%BE%D1%82%D0%B8 %D0%B2%D0%BE%D0%B4%D0%B5%D0%B9%D1%81%D1 %82%D0%B2%D0%B8%D1%8F)).

The composition and characteristics of the electronic suppression complex depend on the purpose of the aircraft and the conditions of combat use. In the general case, the complex of electronic suppression includes:

- channels for reconnaissance and space surveillance (sensors) in optical and radio bands (published on the Internet at https://rostec.ru/news/4516763/);

- executive systems, including devices for emitting passive interference and decoys, for example, "UV-30K", "UV-30MK" (published on the Internet at https://vympelmkb.com/production/production/ustroystva-vybrosa-passivnykh -pomekh/ustroystvo-vybrosa-uv-30mk/), active jamming systems for radar equipment, laser and optical systems for suppressing guided missiles with infrared homing heads (IR seeker) "LSOEP" (published on the Internet at https://rostec .ru/news/4514820/), and "AN/AAQ-24(v) DIRCM" (published on the Internet at https://www.globalsecurity.org/military/systems/aircraft/systems/an-aaq -24.htm).

Known countermeasure systems placed on airplanes and helicopters, for example, on the IL-76MD, SU-25T (Russia), the AH-1F helicopter (USA), consisting of an electronic intelligence station, an infrared (IR) detection station, a radio interference station, a consumable ejection device means, IR interference and a computing device, where they take direction in the radio and IR ranges, analyze the received data and make a decision on countering interference stations in the radio, IR ranges, shooting expendable funds, transmit data for the use of standard weapons (Gordeenko Yu V. et al., Military Aviation, Vol. 1, pp. 6, 158 and 249. Potpourri LLC, 1999). On SU-35 aircraft, the L-175 airborne defense complex is installed, which protects the object during the interaction of a radio interference station, an infrared (IR) detection station, and a consumables ejection device. On Mi-8AMTSh, Mi35M, Ka-52 helicopters, the Vitebsk airborne defense complex provides protection: the system detects a missile launch and activates the use of passive and active protection.

The disadvantage is the separate independent operation of the information collection and suppression systems, which does not allow achieving maximum suppression efficiency. With separate operation of information collection systems, it is possible to multiply targets detected by different systems, while the reliability of information about real targets will be lower.

The objective of the present invention is to organize protection against air defense systems by analyzing information from surveillance systems, automatically managing view areas to provide a circular view of space, setting up dangerous objects for tracking, identifying air defense systems, identifying the type of threatening objects, determining the location and trajectory of movement, as well as the determination of the optimal method of protection and the integrated management of protective equipment, combined with the maneuver of the aircraft.

The technical result of the invention is to increase the effectiveness of aircraft protection.

The claimed technical result is achieved by the invention, which implements a method for automatic integrated control of the protection of an aircraft from air defense systems, including the accumulation and analysis in the analytical control unit of information about the current situation coming from reconnaissance sensors in the radio range, reconnaissance sensors in the IR range, reconnaissance sensors in the UV range, laser irradiation sensors, a radar station, an optoelectronic station, analysis of previously accumulated data on the results of exposure to an executive system of active interference in the radio range, a device for emitting passive interference in the radio range, an active interference device in the IR range, a device for ejecting decoys, a maneuvering control unit, identification in the analytical control block of threat sources and their type and subsequent determination of the method of protection and the moment of generation of control commands for a specific protective system, in this case, either one or a combination of several protective systems can be used, and when several threats of the same type or The analysis-control unit of different types determines the combination of the use of protective systems necessary to protect the aircraft, and the sequence of generating commands to control each of them, taking into account mutual restrictions when they are used together.

The described method is implemented using an automatic complex control system for the protection of an aircraft, including an analytical control unit, a survey system consisting of reconnaissance sensors in the radio range, reconnaissance sensors in the IR range, reconnaissance sensors in the UV range, laser irradiation sensors, a radar station, optoelectronic station, and a protective system consisting of an executive system of active interference in the radio range, a device for emitting passive interference in the radio range, an active jamming device for the IR range, a device for ejecting false targets, and a maneuvering control unit.

The invention is illustrated by a diagram of an automatic complex control system for the protection of an aircraft from air defense means, shown in Fig. 1.

In FIG. 1 the following designations are used:

1 - analytical control unit

2 - reconnaissance sensors in the radio range

3 - reconnaissance sensors in the IR range

4 - reconnaissance sensors in the UV range

5 - laser irradiation sensors

6 - radar station

7 - optoelectronic station

8 - executive system of active radio interference

9 - device for emitting passive radio interference

10 - IR active interference device

11 - decoy ejection device

12 - maneuvering control unit.

The input of the analytical-control unit (1) via the on-board information exchange network receives information from the components (2)-(7) of the survey system, as well as information about the resources used by the aircraft. Depending on the degree of sufficiency of information from different directions, commands are issued from the output of the analytical control unit (1) to assign review sectors or place objects for tracking in components (2) - (7) of the survey system, taking into account their free resources. Depending on the information accumulated in the analytical and control unit (1), the type of threats is determined, their priority range is formed, the calculation and construction of a real-time bypass of the areas of operation of ground-based air defense systems is carried out, the method of protection is determined and the integrated control of components (8) - ( 12) a protective system for influencing the threat with a combination of active jamming, shooting decoys, maneuver control. This takes into account the mutual restrictions on the use of these systems (the use of one system, for example, maneuvering countermeasures, makes it difficult and less effective to use interference from an ejection device). At the same time, tracking failure processes are monitored and the protection method used is adjusted, aimed at enhancing the response to the applied interference and maneuvers.

The present invention allows to provide:

- complex coordinated management of the analytical control unit (1) of the viewing and tracking areas of various components (2) - (7) of the surveillance system to detect the appearance of threats from all angles and at all ranges;

- conducting incidental reconnaissance and accumulation of information from the components (2) - (7) of the survey system, according to the information from which air defense systems are detected, information on them is stored and used during the further work of the analytical control unit (1);

- determination of threat types and ranking in the analytical-control block (1) of the detected objects according to the accumulated information and the formation of priority rows;

- construction is carried out in the analytical control unit (1) bypassing the areas of operation of ground-based air defense systems, calculated in real time according to the parameters of mutual movement and information about objects from the components (2) - (7) of the surveillance system or previously received information during incidental reconnaissance;

- determination in the analytical and control unit (1) of the protection method and the formation of an integrated control of the executive components (8) - (12) of the protective system to influence the threat of a combination of active interference, shooting decoys, maneuver control;

- tracking in the analytical control unit (1) the processes of disruption of tracking and adjusting the protection method used to increase the response to applied interference and maneuver.
