The integrated radar-EO detection system is designed for land border surveillance, coastal and port security, key-area defense, low-altitude UAV monitoring, and perimeter protection of large facilities and critical infrastructure. By combining radar and electro-optical detection, the system supports continuous day/night scanning, video surveillance, electronic mapping, zone and alarm settings, radar-EO linkage, target tracking, and automatic adaptation of field of view and servo speed. It enables long-range detection, early warning, EO verification, and continuous tracking of personnel, vehicles, UAVs, and other targets. The system is especially suitable for all-weather, automated, multi-target surveillance over large areas. It also supports layered detection and identification of different target types through radar detection and EO recognition.
