Low-altitude defense system of unmanned aerial vehicle

Abstract

The invention discloses a low-altitude defense system of an unmanned aerial vehicle. The low-altitude defense system is characterized by comprising a detection and recognition system, a photoelectrictracking system and an interference inversion system, wherein the detection and recognition system is used for performing scanning, detection and early warning of an invading unmanned aerial vehicle;the photoelectric tracking system is used for identifying, tracking and locating the invading unmanned aerial vehicle, and determining the coordinates of the intruding unmanned aerial vehicle; and theinterference inversion system is used for interfering or controlling the unmanned aerial vehicle. In the low-altitude defense system of the unmanned aerial vehicle, multi-sensor fusion front-end signal acquiring equipment is adopted, so that various parameters can be obtained, and the intruding unmanned aerial vehicle can be found and tracked in time. Meanwhile, automatic defense of the unmannedaerial vehicle is realized through linkage among systems.

Description

technical field [0001] The invention relates to the field of anti-drone, in particular to a low-altitude defense system for unmanned aerial vehicles. Background technique [0002] In recent years, low-altitude, slow-speed and small-target unmanned aerial vehicles (UAVs) with multi-rotor aircraft as the main form have developed rapidly. Its aerial photography, volley flight, real-time image transmission, transportation and delivery capabilities have brought new challenges to confidentiality, security and anti-terrorism. challenge. [0003] With the rapid growth of the UAV market, the risk of stealing secrets, security risks, and violent terrorism brought about by the "black flight" of UAVs has become more prominent. The cameras, recordings and some special stealing equipment provided by drones will seriously violate the privacy of passengers and the information security of sensitive areas such as airports and military bases. UAVs invade airports, important places, etc., tra...

AI Technical Summary

Problems solved by technology

[0004] The existing anti-drone technology has the following defects: 1. It focuses on direct destruction, which may easily cause drone crashes and accidental personal and property damage; 2. Since the drone target is small, radar can detect it from a long distance , but it is difficult to accurately track

Optical detection can use visible light to detect targets, or use the target's thermal infrared reflection to detect, which makes optical detection much clearer than radar; 3. The current anti-drone is mainly fixed and lacks mobility; 4. No The type of man-machine detection and identification device is single, and most drones cannot be detected; 5. The interference method adopted is relatively single, and it is impossible to interfere with multiple different types of drones at the same time; 6. The existing anti-drone systems There is no linkage between them, and the automatic defense of drones cannot be realized
