The three-dimensional security system JT 27-5 UAV/Drone Detection Radar searches and finds targets within a radius of 5 kilometers of it. The system automatically finds the target and analyzes its flight characteristics to evaluate the threat of the target. And the system automatically assigns electro-optical equipment to track and identify the high-risk targets. Combining the input of radar and electro-optical equipment, the high-precision data of target position is formed to provide precise guidance information for the anti-UAV equipment. It realizes target positioning on the map, and has trajectory displaying and replaying functions. Positioning includes displaying target distance, position, altitude, flying direction, speed, etc. Detecting distance can be up to 5 km. Advanced modals have longer detecting distance up to 50 km upon client’s request.
