Low altitude detection radar is a detection equipment in the field of UAV prevention and control. The device emits electromagnetic waves to irradiate the target and receive its echo, thereby obtaining the distance, speed, orientation, height and other information from the target to the electromagnetic wave transmitting point, which can form the flight trajectory of the target and provide target position guidance for the long-range high-definition camera or countermeasures equipment. Our radar is equipped with micro-Doppler detection to effectively detect and track hovering or circling drones.
