The fixed "Hawk-eye" FCR-01 runway foreign body detection system adopts advanced system architecture design and unique target detection algorithm, which can realize the rapid detection and initial alarm of small foreign body in all-weather, all-day, long-distance and large-scale runway. The system consists of radar equipment and photoelectric equipment. The radar adopts millimeter wave radar technology. Photoelectric equipment uses remote high-definition night vision camera. A radar and an electro-optical device form a detection point, each covering 450 meters of runway length. The runway of class E airport which is 3600 meters long, can be completely covered by 8 detection points.
