Description

Technical Field

[0001] The utility model relates to the field of electronic countermeasures, in particular to a co-inflatable corner reflector decoy device for a rotary-wing unmanned aerial vehicle. Background Art

[0002] Passive decoy jammers play a crucial role in electronic countermeasures, confusing enemy radars. In the military, foreign countries deploy chaff flares and corner reflectors as decoys to confuse or deceive enemy radars during electronic countermeasures. In actual use, these decoys have strict timing requirements, limited similarity to the simulated enemy platform, poor maneuverability, and low controllability after release. Furthermore, the chaff cloud formed after the chaff flare explodes has a short aerodynamic lifespan.

[0003] Patent publication number CN202256664 U proposes a high-altitude floating integrated active and passive jamming decoy. Although the passive decoy's jamming lasts a long time, it struggles to effectively jam the decoy once released. Furthermore, the decoy is uncontrollable, non-maneuverable, and susceptible to environmental factors such as wind speed. Patent publication number CN 219247856 U proposes a drone-mounted integrated electronic jamming device. While it can utilize a drone to release a corner reflector, offering a certain degree of controllability and maneuverability, the corner reflector is poorly integrated with the drone platform and is susceptible to environmental factors such as wind speed. Furthermore, its heavy weight makes it difficult to deploy the decoy in a cluster to simulate a self-defense platform, limiting the effectiveness of the passive decoy jamming. Utility Model Content

[0004] Based on this, the utility model provides a co-inflatable corner reflector decoy device for a rotor UAV, which integrates the released corner reflector with the UAV body. It can not only ensure the controllability and maneuverability of the passive decoy after release, but also simulate the radar echo characteristics of different platforms through size control such as UAV clusters, thereby improving the deception and interference effect of the passive decoy. At the same time, it can be adjusted in time according to actual needs, and a single UAV is not easily affected by the environment.

[0005] The technical problem to be solved by the utility model is achieved through the following technical solutions:

[0006] A co-inflatable corner reflector decoy device for a rotary-wing UAV comprises a UAV platform, a UAV power supply arranged on the UAV platform, a UAV flight control module, a plurality of UAV rotor motors, a UAV landing gear, and two co-inflatable corner reflector release devices. The UAV power supply is connected to the UAV flight control module, the UAV rotor motor, and the two co-inflatable corner reflector release devices. The two co-inflatable corner reflector release devices are distributed at the upper and lower ends of the UAV platform. The UAV flight control module is used to receive UAV flight instructions and passive interference instructions, control the UAV rotor motor to complete corresponding operations according to the UAV flight instructions, and control the co-inflatable corner reflector release devices to complete the inflation operation and release the corner reflectors according to the passive interference instructions.

[0007] Furthermore, the co-body inflatable corner reflector release device includes a corner reflector filling / exhaust switch and an inflatable corner reflector connected to the corner reflector filling / exhaust switch. After the UAV flight control module receives the passive interference command, it transfers the signal to the co-body inflatable corner reflector release device, turns on the corner reflector inflation switch, and the inflatable corner reflector is inflated to form a corner reflector, reflecting the radar detection signal to form an echo signal; after completing the task, the UAV flight control module receives the gas release command and transfers the signal to the co-body inflatable corner reflector release device, turns on the corner reflector exhaust switch, and releases the gas in the inflatable corner reflector.

[0008] Furthermore, the two co-inflatable corner reflector releasing devices form a regular octahedron, a regular dodecahedron or a regular icosahedron after being inflated.

[0009] The beneficial effects of the utility model are:

[0010] (1) The device can remotely control the drone to release inflatable corner reflectors to reflect the enemy radar echo. It can also simulate the shape and radar echo characteristics of different platforms such as aircraft and ships through the drone cluster, forming a passive false target with the same proportion and similar motion state as the actual platform to interfere with the enemy radar detection.

[0011] (2) The number and shape of the UAV cluster on the simulation platform can be adjusted in real time according to the specific platform parameters. The geographic information, time information, and dynamic route planning of the UAV cluster forming a passive false target can be achieved through remote control.

[0012] (3) When acting as passive decoys, drone clusters have good radar interference effects, long hovering time, high maneuverability, and are recyclable and reusable; individual devices have a high degree of integration and are less affected by the environment. The shared inflatable corner reflector adopts a modular design, is easy to disassemble and assemble, can be replaced as a whole, and is convenient for storage and transportation. At the same time, the gas in the corner reflector can be released remotely after the mission is completed. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0019] Referring to 1-4, the present invention provides a co-existing inflatable corner reflector decoy device for a rotary-wing UAV, comprising a UAV platform 1, a UAV power supply 2 mounted on the UAV platform 1, a UAV flight control module 3, four UAV rotor motors 4, a UAV landing gear 5, and two co-existing inflatable corner reflector release devices 6. The UAV power supply 2 is connected to the UAV flight control module 3, the UAV rotor motors 4, and the two co-existing inflatable corner reflector release devices 6 to provide operating power. The power supply to each functional module is independent of one another, and the capacity of the UAV power supply can be adjusted accordingly based on the requirements of the present invention.

[0020] The UAV flight control module 1 is configured to receive UAV flight instructions and passive jamming instructions, control the UAV rotor motor 4 to perform corresponding operations based on the UAV flight instructions, and control the co-inflatable corner reflector release device 6 to inflate and release the corner reflector based on the passive jamming instructions. The UAV flight instructions include time information, spatial information, and motion instructions for the UAV flight.

[0021] The co-inflatable corner reflector release device 61 includes a corner reflector fill / exhaust switch 61 and an inflatable corner reflector 62 connected to the corner reflector fill / exhaust switch 61. Upon receiving the passive jamming command, the UAV flight control module 1 transmits the signal to the co-inflatable corner reflector release device 6, activates the corner reflector fill switch, and inflates the inflatable corner reflector 62 to form a corner reflector, reflecting radar detection signals and forming an echo signal. Upon completing the mission, the UAV flight control module 1 receives the release command and transmits the signal to the co-inflatable corner reflector release device 2, activates the corner reflector exhaust switch, and releases the gas in the inflatable corner reflector 62. Figure 1 This is a schematic diagram of the structure before releasing the co-inflatable corner reflector. Figure 2 Schematic diagram of the structure after the common inflatable corner reflector is released.

[0022] Since the size of the inflatable corner reflectors of the rotary wing UAV is limited, in practice, the reflection cross-sectional area of the corner reflectors is increased by using a cluster of UAVs to simulate actual aircraft, ships and other platforms. Figure 5 The figure shows an example of a swarm of 19 drones simulating a ship. After the 19 drones release their shared inflatable corner reflectors, the overall echo signal is enhanced, effectively mimicking the echo of a ship and deceiving enemy radar.

[0023] The number of the drone cluster can be set according to the size of a single drone, the size of the drone's common inflatable angular emitter and the size of the simulation platform. The distribution shape of the drone cluster is set in advance according to the echo signal characteristics of the simulation platform. After the overall bait is formed, the movement state of the drone cluster can be kept consistent with the simulation platform through remote control, and control adjustments can be implemented according to actual needs.

[0024] The shape of the co-body inflatable corner reflector release device 61 can be half of a regular octahedron, a regular dodecahedron, a regular icosahedron, etc., and is distributed at the upper and lower ends of the UAV platform 1. The co-body inflatable corner reflector release device 6 can be recycled and replaced.

[0025] The utility model can simulate fixed and mobile platforms in the air, on the water surface and on the roadbed. After completing the deception mission, the drone cluster can be recovered and reused as a whole.

[0026] The utility model can form a cluster to deceive and interfere with radar detection equipment alone, and can also cooperate with other electronic jamming measures to carry out deception and interference. It has the characteristics of good deception effect, high controllability, good maneuverability, and high economic benefits.

[0027] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention are intended to be covered by the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
