The UAV detection radar operates in the Ku band and is a three-dimensional radar system capable of detecting and warning against low-altitude, slow-moving, small targets (referred to as low-slow-small targets) in all weather and all time. This radar uses a fully coherent pulse Doppler technology system, with azimuth mechanical scanning covering 360° of the entire airspace and pitch rapid phase scanning to achieve wide-range airspace coverage. Using TR technology, digital synthesis technology, long-term accumulation and tracking technology, target detection technology under low signal-to-noise ratio, clutter suppression technology, and other technologies, it can achieve all-round, high-precision and stable detection of low-slow-small targets such as UAVs, and obtain real-time information such as target distance, azimuth angle, height, and speed.
