Compared with products of the same type, it has the advantages of high precision, high data rate, high detection probability, low false alarm rate, follow-up gaze, good portability, and rapid deployment. The five-kilometer low-altitude radar can accurately detect and track low-slow and small targets such as UAVs, display and output multi-dimensional information such as distance, azimuth, pitch, speed, altitude, and intensity of the target, forming a three-dimensional movement situation of low-altitude targets . The five-kilometer low-altitude surveillance radar adopts a one-dimensional phased array system and has the ability to detect a variety of aircraft such as UAVs, fixed-wing UAVs, model aircraft, and self-assembled machines. This product has the ability to detect multiple targets and complex urban environments. At the same time, this product can output the target track information to the optoelectronics, command center, etc. through a predetermined interface protocol, providing precise guidance for and strike equipment。
