Description

Technical Field

[0001] This utility model relates to the field of optoelectronic countermeasures technology. Specifically, this utility model relates to a laser decoy capable of hovering, accompanying, or combining hovering and accompanying functions, and a laser-guided deflection system including the laser decoy. Background Technology

[0002] With the widespread use of laser-guided weapons, countering laser-guided weapons has become one of the key areas of development in optoelectronic warfare.

[0003] In existing technologies, the technical solutions for jamming semi-active laser-guided missiles include two types: jamming schemes and deflection-induced jamming schemes. The laser deflection-induced jamming scheme is implemented through unit operations including the following:

[0004] Laser alarm device → Laser signal integrated processor → Laser jamming signal transmitter → Laser decoy

[0005] The laser warning device receives the signal (laser-guided target indication signal) that is irradiated onto the protected target by the opponent's laser equipment (target indicator); the laser signal integrated processor obtains information such as the angle, repetition frequency, code pattern, and arrival time of the irradiated laser signal by processing the intercepted signal; the laser jamming signal transmitter (laser) replicates the laser signal with the same technical parameters as the opponent's laser irradiation signal; the laser decoy has a diffuse reflector or natural object with the ability to scatter the wavelength of the irradiated laser at a wide angle (Liu Jingjiao, Optoelectronic Countermeasures Technology and Systems, China Science and Technology Press, 2004.6, pp. 143-144).

[0006] Existing technologies, including laser-guided deflection technology that uses diffuse reflectors to emit lasers as decoys, generally suffer from problems such as low laser-guided deflection efficiency, poor deployment convenience of laser-guided deflection systems, and suitability only for fixed target protection. Utility Model Content

[0007] The technical problem to be solved by this invention is to provide a highly efficient laser decoy suitable for protection of mobile targets and a laser-guided deflection system including the decoy.

[0008] This utility model provides a hovering and / or accompanying laser decoy, including a laser, a decoy head, and a carrier. The laser includes a connection part between the laser and the decoy head. The decoy head includes a laser scatterer, a base, and a connection part with the laser. The connection part between the laser and the decoy head is configured to allow the laser and the decoy head to be connected as an integral assembly. The laser emitted by the laser irradiates the decoy head and is partially or completely scattered by the laser scatterer therein.

[0009] This utility model provides a laser-guided deflection system, including a first functional unit and a second functional unit. The first functional unit is a combination of a laser alarm, information processing, and an instruction module. The second functional unit is a hovering and / or accompanying laser decoy. Their configuration satisfies the following: the first functional unit detects and processes the laser-guided target indication signal, generates a laser-guided deflection instruction, and transmits the instruction to the second functional unit. The second functional unit emits and scatters deflection interference laser according to the instruction. The hovering and / or accompanying laser decoy includes a laser, a decoy head, and a carrier. The laser includes a connection part between the laser and the decoy head. The decoy head includes a laser scatterer, a base, and a connection part with the laser. The connection part between the laser and the decoy head is configured such that the laser and the decoy head are connected as a single unit. The laser emitted by the laser irradiates the decoy head and is partially or completely scattered by the laser scatterer therein.

[0010] According to the hovering and / or accompanying laser decoy or laser-guided deflection system provided by this utility model, in one specific embodiment, the laser scatterer includes a first reflector and a second reflector. The arrangement of the first reflector and the second reflector in the decoy head satisfies the requirement that part or all of the deflection interference laser irradiating the decoy head is reflected by the first reflector to the second reflector.

[0011] In this invention, the decoy head in the instant-disposable laser decoy or laser-guided deflection system includes a housing.

[0012] In this invention, the transmission in the laser-guided polarization system is either wired or wireless.

[0013] In this invention, the instant-disposable laser decoy and the laser-guided deflection system each include a power supply, or they share one.

[0014] The decoy provided by this invention, and the deflection system including the decoy, are particularly suitable for laser-guided deflection protection of moving targets. Attached Figure Description

[0027] A1 First reflector B1 Second reflector Detailed Implementation

[0028] The specific embodiments of this utility model are described below. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0029] In this invention, the setting includes design and / or arrangement; the scattering includes reflection, transmission and possible refraction; the reflection includes specular reflection, diffuse reflection and directional reflection (reflection types between specular reflection and diffuse reflection).

[0030] Compared to traditional decoy deployments using diffuse reflectors or fiber optic laser beams, the hovering and / or accompanying laser decoy described in this invention is an optoelectronic countermeasures system specifically designed to provide anti-missile protection for mobile targets, including moving equipment, in a battlefield environment. This system accompanies the equipment to be protected, either by accompanying it while it is moving or by hovering it while it is stationary, to deflect attacks from laser-guided weapons. The vehicle used includes, but is not limited to, balloons, gliders (or drones), etc.

[0031] Figure 1 a and b are schematic diagrams of two hovering and / or accompanying laser decoys provided by this utility model.

[0032] Figure 1 The hovering and / or accompanying laser decoy shown in diagram a includes a laser 1, a decoy head 2, and a carrier 3. The carrier 3 is a drone, and the laser decoy is mounted on the drone's fuselage.

[0033] Figure 1 The hovering and / or accompanying laser decoy shown in b includes a laser 1, a decoy head 2, and a carrier 31. The carrier 31 is a drone, and the laser decoy is suspended and mounted on the drone's body.

[0034] According to this utility model, the structure and composition of the decoy head, including laser scattering bodies, are not limited, provided that the laser irradiated into the decoy head is partially or completely scattered.

[0035] In one specific embodiment, the laser scatterer includes a first reflector and a second reflector. The arrangement of the first and second reflectors in the decoy head satisfies the following condition: all or part of the laser light irradiating the decoy head is reflected by the first reflector and then reflected by the second reflector. Preferably, the first reflector is a specular reflector, and its arrangement in the decoy head includes its optical axis coinciding with the optical axis of the irradiated laser beam; preferably, the second reflector is a diffuse reflector or a directional reflector.

[0036] Figure 2 A laser and decoy head assembly suitable for use in this utility model, and a schematic diagram of the optical principle of the decoy head therein.

[0037] Figure 2 The assembly shown includes a decoy head 4 and a laser body 8. The decoy head 4 includes a first reflector (also called a first deflection interference laser reflector) A1, a second reflector (also called a second deflection interference laser reflector) B1, a base 5, a housing 6, and a laser connection part 7. The laser body 8 includes a decoy head connection part 9.

[0038] according to Figure 2 The first reflector A1 and the second reflector B1 in the decoy head are two concentric circular reflectors with their reflecting surfaces facing each other, and the optical axis of the first reflector coincides with the optical axis of the deflection interference laser beam irradiated by the laser.

[0039] like Figure 2 As shown, the decoy head includes a housing. When the decoy head includes a housing, the housing can simultaneously serve to fix and support each laser reflector.

[0040] When the decoy head does not include the housing, the method of fixing and supporting the laser reflector is not limited, provided that the overall laser deflection and performance (including appearance and ease of use) of the decoy head are not affected. For example, the laser reflector can be molded into a single piece and then assembled with the base.

[0041] according to Figure 2Laser 8 emits a deflection interference laser 10, which enters the decoy head 4 through the laser input port O. This deflection interference laser is reflected by the first reflector A1, and the reflected laser 12 is reflected a second time by the second reflector B1 to become a secondary reflected laser 13. Optionally, the first reflector A1 can be a laser transmitter / reflector. When the first laser reflector A1 is a laser transmitter / reflector, a portion of the deflection interference laser entering the decoy head from the laser is directly emitted into the upper airspace as a transmitted laser 11, and together with the secondary reflected laser 13 (including any possible portion of the primary reflected laser 12 that is not secondary reflected), constitutes a... Figure 3 The polarization interference laser 16 described herein.

[0042] Figure 3 A flowchart illustrating the structure and workflow of a laser-guided deflection system provided by this utility model.

[0043] according to Figure 3 The laser-guided deflection system provided by this utility model includes a first functional unit and two second functional units. The first functional unit captures the laser target indication signal 14 and generates a laser-guided deflection command. This command is transmitted (or wirelessly transmitted) to the second functional unit via the laser-guided deflection command transmission line 15. The second functional unit then emits and scatters deflection interference laser 16 according to the command.

[0044] In this invention, the transmission of the deflection command between the first functional unit assembly and the second functional unit assembly in the laser-guided deflection system is either wired or wireless.

[0045] Generally, the first functional unit in the laser-guided deflection system is designed as a non-damage-causing component, while the second functional unit (the hovering and / or accompanying decoy in this invention) is designed as a damage-causing component (a false target for laser-guided weapon attacks). Therefore, in actual combat, the distance maintained between the first and second functional units in the system must be greater than the explosive kill radius of the projectile; for example, this distance should be greater than 30 meters, preferably greater than 50 meters.

[0046] exist Figure 3 In the laser-guided deflection system shown, the transmission of deflection commands between the first functional unit and the second functional unit (the hovering and / or accompanying decoy in this invention) is wired. The transmission wire can be, but is not limited to, 30 meters or more and less than or equal to 300 meters; preferably, 50 meters or more and less than or equal to 150 meters. Correspondingly, when the deflection commands are transmitted wirelessly, the wireless transmission distance of the wireless signal transmission device provided in the system can be, but is not limited to, 30 meters or more and less than or equal to 300 meters; preferably, 50 meters or more and less than or equal to 150 meters.

[0047] Provided that the distance between the first functional unit assembly and the second functional unit assembly is greater than the explosive kill radius of the projectile, this invention does not restrict the specific arrangement of the first functional unit assembly, including the laser warning, information processing, and command module assembly. The assembly can be compact or loosely integrated with other battlefield command and control systems (including those protecting the target) in an embedded manner. "Loosely integrated" means that, while ensuring the overall functionality of the system, structural and spatial compactness between the modules in the assembly is not pursued. "Compact" means that the assembly, as a whole, emphasizes its compactness. That is, the modules are tightly connected, typically with few or no gaps, intervals, or redundant parts.

[0048] As an exception, the first and second functional units of the laser-guided deflection system provided by this invention can be combined into a single unit, which incorporates an automatic control system. In application, this unit is released as a damaged component (a decoy target attacked by a laser-guided weapon) and hovers and / or accompanies the target to be protected at a distance greater than the explosive kill radius of the projectile.

[0049] In this invention, the laser alarm, information processing, and instruction modularization technology in the first functional unit, and the laser in the second functional unit are existing technologies and will not be described in detail here.

[0050] In this invention, the laser decoy and the laser-guided deflection system each include a power supply, or they share one.

[0051] Provided that the power supply requirements of the laser decoy and laser-guided deflection system are sufficiently met, this invention does not impose any restrictions on the power supply.

[0052] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple changes can be made to the technical solution of the present invention, and all such simple changes fall within the protection scope of the present invention.
