Radar-based anti-UAV defense system

Abstract

The invention discloses a radar-based anti-UAV defense system, which comprises a detection and recognition system, a photoelectric tracking system and an interference countering system. The detectionand recognition system comprises a detection radar, an audio detector and a spectrum detector; the photoelectric tracking system comprises a gyro stable turntable, an optical tracking device and an infrared tracking device, the optical tracking device and the infrared tracking device are respectively installed on the gyro stable turntable, the infrared tracking device is used for identification and tracking at night, the optical tracking device adopts a 37 times continuous zoom high definition television camera, the infrared tracking device adopts a high-resolution infrared thermal imager, theinterference countering system includes an electromagnetic pressing system, and the electromagnetic pressing system includes a directional multi-interference source interference countering system. The radar-based anti-UAV defense system can discover and track the invading UAV in time, and at the same time, the linkage between the various systems realizes the automatic defense of the UAV.

Description

Technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a radar-based anti-UAV defense system. Background technique [0002] In recent years, low-altitude, slow-moving, small-target UAVs with multi-rotor aircraft as the main form have developed rapidly. Its aerial camera, volley arrival, real-time image transmission, and transportation delivery capabilities have brought new ideas to confidentiality, security, and anti-terrorism. challenge. [0003] With the rapid growth of the drone market, the risks of secret theft, security, and violent terror brought by the "black flying" of drones have become more prominent. Cameras, recordings and some special stealth equipment provided by drones will seriously infringe on passenger privacy and the information security of sensitive areas such as airports and military bases. Drones invade airports, important places, etc., to track and photograph the whereabouts of residents, seriously ...

AI Technical Summary

Problems solved by technology

[0005] 1. Emphasis is placed on direct destruction, which is likely to cause drone crashes and accidental personal and property damage;

[0006] 2. The current anti-drone is mainly fixed and lacks mobility;

[0007] 3. The type of UAV detection and identification device is single, and most UAVs cannot be detected;

[0008] 4. The interference method used is relatively simple, and it is impossible to interfere with multiple different types of drones at the same time;

[0009] 5. There is no linkage between the existing anti-drone systems, and it is impossible to realize the automatic defense of drones
