Description

The invention relates to methods for combined camouflage of a surface ship (NK) from radar, radio engineering and optoelectronic means for detecting and homing anti-ship cruise missiles (RCC).

Known methods of radio-optical camouflage (ROM) NK using fired upon the attack of a surface ship RCC combined false targets (LC) such as dipole reflectors (interference to active radar channels RCC), generators of infrared interference, smoke and aerosols (interference to the optoelectronic channels RCC), specialized transmitters of active interference (interference with passive radio engineering and active radar channels of RCC) - see, for example, A.B. Shirokorad "Domestic mortars and rocket artillery." Mn., Harvest / M., ACT, 2000, pp. 393-399 (ZIF-121 / KL-102 complex), pp. 399-407 (A-223 "Snow" complex), pp. 407-409 (PK-10 complex).

However, fired LCs have a limited time range of regular functioning, limited to units of minutes, require a certain deployment time, and are subject to the influence of wind, precipitation, sea waves.

Known controlled unmanned aerial vehicles (LA) of various aerodynamic, energy-moving and structural layout schemes that can potentially be used for the ROM of various objects. In particular, a tethered vertical take-off aircraft with the automatic stabilization system MPVVA is known - see, for example, S.M. Ganin, A.V. Karpenko, V.V. Kolnogorov, G.F. Petrov “Unmanned Aerial Vehicles”, St. Petersburg, “Nevsky Bastion”, 1999, p. 136.

Also known are the ROM NK methods using specialized traps. The trap is a technical tool that simulates NK in the spectral ranges of the homing heads (GOS) of RCC. In particular, a trap towed by a ship on a water surface is presented in the monograph: A.I. Paly "Radio electronic warfare", second edition, M., Military Publishing House, 1989, p. 90, Fig. 4.2 (d) is the closest analogue.

However, the method - the closest analogue does not provide radio-optical masking of NK from RCC at the bow heading angles, cannot be used effectively with strong excitement of the water surface and high values of the speed of the NK.

The technical task of the invention is the implementation of a continuous continuous all-azimuthal radio-optical masking of NKs in motion and in the parking lot from anti-ship missiles, including in several spectral ranges at the same time.

длины корпуса НК летательный аппарат-электролет многовинтовой вертолетной схемы, при этом ЛА заблаговременно выводят на полную длину кабеля в направлении, перпендикулярном угрожаемому азимуту атаки ПКР, от НК по кабелю осуществляют электропитание и управление ЛА, источники активных и пассивных помех опускают с ЛА на тросе до высоты не более 30 м от поверхности воды и активируют по команде с НК по факту атаки надводного корабля ПКР. Дополнительно на ЛА могут размещаться не менее одного сбрасываемого уголкового отражателя либо линзы Люнеберга, которые сбрасывают по команде с НК по факту атаки надводного корабля ПКР. Также на кабель связи ЛА с НК на расстоянии до

длины кабеля со стороны ближайшего к НК ЛА могут подвешиваться один или более уголковый отражатель или линза Люнеберга. Кроме того, на ЛА могут подвешиваться переизлучающие антенные решетки. Допускается размещение на ЛА блоков сбрасываемых дипольных отражателей, которые последовательно сбрасывают по команде с НК по факту атаки надводного корабля ПКР. Возможно оснащение ЛА стационарным либо сбрасываемым генератором инфракрасных (ИК) помех, который активируют по команде с НК по факту атаки надводного корабля ПКР. На ЛА либо кабеле связи с НК допускается размещение не менее четырех переотражателей лазерного излучения. Дополнительно на ЛА может размещаться генератор дыма или аэрозоля, который активируют по команде с НК по факту атаки надводного корабля ПКР. В ряде случаев ЛА периодически перемещают вдоль угрожаемого азимута атаки ПКР со скоростью, близкой текущей скорости НК. Также каждый винт ЛА либо весь блок винтов ЛА может закрываться кольцеобразным обтекателем. При одновременном задействовании с одного НК ЛА на двух кабелях связи с НК, их располагают на перпендикулярных азимутах, а при одновременном задействовании с одного НК ЛА на трех и более кабелях связи - их располагают в азимутальной плоскости асимметрично НК.This goal is achieved by the fact that as a trap use one or more connected to the SC through a cable of at least

the aircraft hull length is a multi-rotor helicopter-type aircraft-electrolyte, in which case the aircraft are brought out in advance to the full cable length in the direction perpendicular to the threatened azimuth of the RCC attack, the aircraft is powered and controlled by the aircraft, the sources of active and passive interference are lowered from the aircraft to the cable to heights of not more than 30 m from the surface of the water and are activated upon command from the NK upon the attack of the surface ship of the RCC. In addition, at least one resettable angular reflector or a Luneberg lens can be placed on the aircraft, which are reset on command from the NK upon the attack of the surface ship of the RCC. Also on the communication cable of the aircraft with the NK at a distance of

cable lengths from the side closest to the low flying aircraft can be suspended by one or more corner reflectors or Luneberg lenses. In addition, re-emitting antenna arrays can be suspended on the aircraft. It is allowed to place on the aircraft blocks of resettable dipole reflectors, which are subsequently reset on command from the NK upon the attack of the surface ship of the RCC. It is possible to equip the aircraft with a stationary or resettable infrared (IR) noise generator, which is activated upon command from the NK upon the attack of the surface ship of the RCC. It is allowed to place at least four laser reflectors on an aircraft or a communication cable with an NK. Additionally, a smoke or aerosol generator can be placed on the aircraft, which is activated upon command from the NK upon the attack of the surface ship of the RCC. In some cases, aircraft periodically move along the threatened azimuth of the RCC attack at a speed close to the current NK speed. Also, each aircraft propeller or the entire aircraft propeller block can be closed with an annular fairing. When simultaneously operating from one NK aircraft on two communication cables with the NK, they are placed on perpendicular azimuths, and while simultaneously using from one NK aircraft on three or more communication cables, they are placed asymmetrically in the azimuthal plane of the NK.

In FIG. 1-4 shows the implementation of the proposed technical solution (Fig. 1 is a side view of the aircraft, Fig. 2 is a front view of the aircraft, Fig. 3 is an enlarged view of the aircraft, Fig. 4 is a top view of the aircraft).

Designations accepted:

1 - surface ship;

2 - LA-electric multi-rotor helicopter circuit;

3 - source of interference;

4 - cable;

5 - communication cable NK - LA;

6 - corner reflector (Luneberg lens);

7 - re-emitting antenna array;

8 - cloud of dipole reflectors;

9 - infrared interference generator;

10 - laser reflector;

L is the length of the hull;

And - the distance of the aircraft from the NK with the normal functioning of the ROM NK.

In FIG. 1 shows a diagram of ROM NK pos. 1 in side view. LA pos. 2 (one or more) are placed at a distance of A≥L / 2 from the SC pos. 1. During normal operation, the source of interference (active and / or passive) pos. 3 omitted from the aircraft pos. 2 on the cable pos. 4 to a height of not more than 30 m from the water surface (imitation of the characteristic “brilliant points” or intrinsic radiation of NK). Power supply and control of the aircraft pos. 2 is carried out with NK pos. 1 through the cable pos. 5 with a length of at least L / 2 (the specified length ensures the fulfillment of the condition under which an unlimited number of anti-ship missiles can be removed to the interference source pos.

длины кабеля поз. 5 со стороны ЛА поз. 2 формирует конкурирующую с НК поз. 1 по эффективной поверхности рассеяния в радиолокационном диапазоне работы ГСН ПКР область, что приводит к промаху ПКР, ориентирующихся на энергетический центр «скопления блестящих точек». Сбрасываемые с ЛА поз. 2 уголковые отражатели (линзы Люнеберга) поз. 6, в том числе плавающие, позволяют еще более расширить зону радиолокационной маскировки НК поз. 1 в угрожаемый период атаки ПКР. Аналогично, на ЛА поз. 2 могут размещаться опускаемые на тросе поз. 4 переизлучающие антенные решетки поз. 7, которые используются в режиме переизлучения принимаемых радиолокационных сигналов ГСН ПКР. Для увеличения интенсивности переизлучаемых сигналов могут применяться специализированные усилители, которые при необходимости дополнительно модулируют сигналы по амплитуде, фазе и частоте. ЛА поз. 2 при защите НК на острых курсовых углах целесообразно располагать на расстоянии A≈L/2, что обеспечивает увод от НК поз. 1 неограниченного количества ПКР.In FIG. 2 shows a diagram of ROM NK pos. 1 in front view. Are shown stationary (mounted on the aircraft pos. 2 and / or cable pos. 5 with the farthest from the pos. 1 side) or discharged from the aircraft pos. 2 Luneberg corner reflectors / lenses, pos. 6. This placement of stationary corner reflectors (Luneberg lenses) pos. 6 - at a distance of

cable length pos. 5 from the side of the aircraft pos. 2 forms competing with NK pos. 1 over the effective scattering surface in the radar range of the GOS RPC operation, which leads to missed RCCs oriented toward the energy center of the “cluster of brilliant points”. Discharged from the aircraft pos. 2 corner reflectors (Luneberg lenses) pos. 6, including floating ones, make it possible to further expand the zone of radar masking of NK pos. 1 during the threatened period of the RCC attack. Similarly, on the aircraft pos. 2 can be placed lowered on the cable pos. 4 re-emitting antenna arrays pos. 7, which are used in the re-emission mode of the received radar signals of the GOS RCC. To increase the intensity of re-emitted signals, specialized amplifiers can be used, which, if necessary, additionally modulate the signals in amplitude, phase and frequency. LA pos. 2, when protecting NK at sharp heading angles, it is advisable to place them at a distance of A≈L / 2, which ensures withdrawal from the NK pos. 1 unlimited number of RCC.

On the cable pos. 5 communication aircraft pos. 2 with NK pos. 1 can also accommodate at least four light laser reflectors pos. 10. Here we use the effect of a horizontal group of “brilliant points” of reflection, which imitates a linearly extended object in the range of active laser locators of the RCC.

In FIG. 3 shows the view of the aircraft pos. 2 (option) enlarged. The cable pos. 5 communication with NK pos. 1, suspended on a cable pos. 5 from the side of the aircraft pos. 2 corner reflector / Luneberg lens (stationary version) pos. 6, laser reflectors, pos. 10 (at least four), and also suspended from the aircraft pos. 2 on the cable pos. 4 IR noise generator pos. 9.

It should be noted that the aircraft pos. 2 can be used as remote from NK pos. 1 platform for the formation in the endangered period of clouds of dipole reflectors pos. 8. In this case, the multi-rotor helicopter circuit of each aircraft pos. 2 allows you to quickly and efficiently disperse single dipoles (usually made of metallized paper, synthetic or glass fiber, aluminum foil and other similar materials) with an air stream, which accelerates the formation of clouds of dipole reflectors pos. 8 required volume and configuration.

To conceal NK pos. 1 from the optical (infrared and visible wavelength range) GOS RCC, including with matrix photodetectors, on the aircraft pos. 2 generators of single-color or multi-color smoke and / or aerosol can be installed, which activate on command from NK pos. 1 upon the attack of the surface ship of the RCC.

In order to simulate the movement of the NK pos. 1 (according to the Doppler frequency shift along the direction of location) - LA pos. 2 with interference sources pos. 3 can periodically reciprocate with a speed ΔV equal to the speed of the pos. 1, along the threatened azimuth. In this case, to exclude the selection of ROM elements by the Doppler frequency offset of the rotary propellers of aircraft 2 - it is advisable to cover them with annular fairings (for example, annular for each screw or common in the outer contour of the area swept by the screws).

It should be noted that the external power supply of each aircraft electro-pos. 2 allows them to be in the air for at least several hours (and even tens of hours). In this case, a periodic change in aircraft poses is allowed. 2 to maintain the regime of constant ROM NK pos. one.

In FIG. 4 presents a view of NK pos. 1 on top with a deployed ROM system based on three aircraft pos. 2. Moreover, the aircraft pos. 2 are located relative to the protected NK pos. 1 as follows. When operating from one NK pos. 1 LA pos. 2 on two communication cables pos. 5 - they are located at approximately perpendicular azimuths. When operating from one NK pos. 1 LA pos. 2 on three or more communication cables, pos. 5 - they are placed in the azimuthal plane asymmetrically NK pos. 1. Thus, a constant all-azimuthal radio-optical masking from RCC NK pos. 1 in motion and in the parking lot.

The application of the proposed technical solution seems appropriate for surface ships and vessels of predominantly medium and large tonnage, which are priority objectives for the RCC. At the same time, the proposed method of radio-optical masking allows the NK in motion and in the parking lot to permanently (constantly) provide all-azimuthal cover from attacks of an unlimited number of anti-ship missiles, including those equipped with multi-spectral seekers.
