DRS-BU002 High-End Anti-Drone System is an upgraded version based on DRS-BU001 for drone defense and critical area protection. Adopting advanced 3D pulse doppler radar, the system has extended detection range dramatically. The system mainly consists of Detecting Unit, Jamming Unit and Camera Unit. The Detecting Unit, which employs the advanced 3D pulse doppler radar, can detect and track long-distance drones, in both horizontal angle and vertical angle. Guided by the accurate drone position information, the Jamming Unit with tall antenna and low power jammer will interfere with the remote control signals and navigation signals of the drone and force it to land or return. The Camera Unit can efficiently record the tracks of the detected drone for further analysis, and also assist the Detecting Unit for more accurate monitoring.
