Abstract

The invention provides an electronic interference device, an unmanned aerial vehicle and a self-defense protection method and device of the unmanned aerial vehicle. By the method, a corresponding interference signal is generated by detection and separation of anti-unmanned aerial vehicle radars, and the unmanned aerial vehicle cannot be captured and / or traced by the anti-unmanned aerial vehicle radars. The self-defense protection device comprises a radio frequency transceiving module, an upper and low variable frequency module, a digital receiver, a signal processing module and a power amplification module. The device is integrally arranged on the unmanned aerial vehicle to achieve running of the unmanned aerial vehicle. The self-defense protection device is small in volume, light in weight and low in power consumption, and the limitation of carrying weight and volume condition of the unmanned aerial vehicle is overcome. With the adoption of the self-defense protection method and self-defense protection device of the unmanned aerial vehicle, the flight safety of the unmanned aerial vehicle can be effectively ensured, the self-defense protection of the unmanned aerial vehicle is achieved, and the unmanned aerial vehicle is enabled to smoothly and safely execute a task; and huge economic and military significance is generated for the unmanned aerial vehicle with million construction cost and smooth completion of an important military task.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle protection, in particular to an electronic interference device, an unmanned aerial vehicle and its self-defense protection method and device. Background technique [0002] At present, fighter jets and bombers are generally equipped with electronic jamming devices, which are used for self-defense of the aircraft, complete electronic jamming of detection radars, and ensure their own safety and the completion of flight missions. [0003] In current and future military missions, the application of large unmanned aerial vehicles (UAVs) is becoming more and more extensive, and UAVs are also beginning to perform missions of great strategic significance. However, the detection and tracking of drones by various prevention and control radars has become the biggest threat to the safety of drones and their missions. Electronic jamming drones are mainly used to jam drones that detect and track drones. ...
