Decoying countering system and method of unmanned aerial vehicle

Abstract

The invention relates to the field of radio navigation, and discloses a decoying countering system of an unmanned aerial vehicle. The system comprises an integrated control device and an unmanned aerial vehicle detection device, a suppression interference signal generating and transmitting device, a navigation decoying signal generating and transmitting device connected with the integrated controldevice. The unmanned aerial vehicle detection device is used for discovering and tracking the unmanned aerial vehicle; the suppression interference signal generating and transmitting device is used for generating and transmitting a radio suppression interference signal; the navigation decoying signal generating and transmitting device is used for generating and transmitting a satellite navigationdecoying signal; and the integrated control device judges whether the unmanned aerial vehicle enters a protective region or not after the unmanned aerial vehicle detection device finds the unmanned aerial vehicle, and controls on / off of the suppression interference signal and the navigation decoying signal according to a certain timing sequence once the unmanned aerial vehicle enters the unmannedaerial vehicle protective region, so that decoying or after-decoying forced landing of the unmanned aerial vehicle is realized.

Description

technical field [0001] The invention relates to the field of radio navigation, in particular to an unmanned aerial vehicle decoy countermeasure system and method. Background technique [0002] In recent years, unmanned technology and platforms have extended to sea, land, air, space and other fields, among which unmanned aerial vehicles are undoubtedly the fastest-growing among many unmanned platforms. With the widespread application of unmanned aerial vehicles and national policies The gradual development of low-altitude airspace, the "black flying" and abuse of drones have also caused safety hazards to the country, society and people. At present, traditional anti-aircraft weapon systems and electronic jamming are generally used for UAV strike and protection technologies. Traditional weapon strike methods are an overkill for micro-UAV targets, which is a typical "cannon and mosquito" tactic. Leading to a huge cost asymmetry problem. Especially when the invading UAVs are sw...

Problems solved by technology

At present, traditional anti-aircraft weapon systems and electronic jamming are generally used for UAV strike and protection technologies. Traditional weapon strike methods are an overkill for micro-UAV targets, which is a typical "cannon and mosquito" tactic. lead to huge cost asymmetries

Especially when the invading UAVs are swarm-type UAV formations, due to the high difficulty of target detection and identification, the reaction time left for the combatants and the system is extremely short, resulting in a significant reduction in protection efficiency and cannot resist small, cheap and unmanned aerial vehicles. Flight Invasion of Human-Machine Swarms

Secondly, it is difficult to realize the forced landing of drones by means of electronic interference
