Embodiment

[0064] (1) After the system is started, it is initialized, the establishment and correction of the coordinate system are completed, and the electromagnetic environment of the target protection space is memorized. The UAV early warning and identification device started to work.

[0065] (2) During the monitoring process of the UAV early warning identification device, the low-altitude early warning radar found suspicious flying objects in the target protection space, and the electromagnetic monitoring equipment found unfamiliar electromagnetic signals in the electromagnetic environment, and the acoustic identification device captured the characteristic noise signal of the UAV . The early warning device fuses and analyzes the sensor information, judges that the intruding object is a drone, and immediately sends an early warning signal to the console. The console receives the early warning signal, turns on the laser ranging radar, and the laser ranging radar at the designated pos...

Abstract

The invention discloses a directional optical interference system for an unmanned aerial vehicle. The directional optical interference system comprises an unmanned aerial vehicle early warning and identifying device, an unmanned aerial vehicle positioning and locking device, a directional interference device, a control panel and an energy device. The unmanned aerial vehicle interference technologyis improved, the directional optical interference is carried out on the unmanned aerial vehicle, the problem that the current unmanned aerial vehicle interference means is single and cannot perform the optical interference on the invaded unmanned aerial vehicle be effectively, and the information of the target area cannot be protected is solved. Meanwhile, the directional interference is carriedout on the invaded unmanned aerial vehicle, and the interference signals are directionally transmitted to the invaded unmanned aerial vehicle, the loss of energy and the optical pollution to the protection region is avoided, and the normal running of the production life in the protection region is guaranteed.

Description

technical field [0001] The invention relates to the technical field of UAV interception, in particular to a method and related devices for UAV optical interference. Background technique [0002] Whether it's for military, commercial, agricultural or home photography, the use of drones in every field is exploding. Especially in aerial photography, environmental monitoring, power inspection, disaster rescue, news reporting, express logistics, remote sensing mapping and other fields are widely used. At the same time, well-known domestic companies such as DJI, Zero, Baidu, Tencent, Xiaomi, and JD.com have also stepped into the drone industry one after another. Some experts even predict that as the price of drones gradually decreases, in the future, one drone per person may become Reality. According to experts' prediction, by 2020, the market space for mass consumer drones will be 26 billion yuan, the market space for professional enthusiasts will be 4 billion yuan; the market ...
