The invention discloses a civil small unmanned aerial vehicle detection and countering system, which combines an active pulse Doppler radar and a high-power signal jammer, performs information exchange and decision through a control display terminal system, can well judge information such as orientation, height, speed, type and the like of a target flyer, and improves the detection and countering efficiency of the target flyer. A corresponding decision can be made according to a detection result, so that detection, interference and countering are integrated, and the problems that a traditional civil small unmanned aerial vehicle interference system detects surrounding unmanned aerial vehicles through a communication spectrum, the interference azimuth is not strong, the accuracy is not high, and the interference and countering efficiency ratio is low are solved.
Description
technical field [0001] The invention belongs to the technical field of pulse Doppler radar and signal interference and countermeasure, and in particular relates to a detection and countermeasure system of a small civil unmanned aerial vehicle. Background technique [0002] In recent years, with the advancement of UAV technology, the civilian small UAV industry has developed rapidly, but the problems of safety and information protection brought about by it have become more and more prominent. On the one hand, incidents of civilian small UAV black flights occur frequently, posing a serious threat to no-fly areas including airports, politically sensitive areas, military management areas, nuclear industry facilities, prisons, and border defenses; on the other hand, malicious small civilian drones UAV flight also poses a greater threat to information security in the fields of electric power, petroleum and other industries, major security activities, major criminal cases, urban ma...
