One of the most important safeguards for flight safety is the detection of foreign object debris. In view of the development trend, the multi-source detection system of "radar + photoelectric" is the development direction of foreign body detection on airport runway. It is urgently needed to have a high integration and coordination of integrated equipment. Based on the principles of photoelectric detection and millimeter wave detection, designed through irregular antennas, the detection capability of millimeter wave and optical detection is efficiently allocated, and the configuration of millimeter wave antenna aperture and optical detection lens is reasonably planned, the co-design and optimization of optical imaging system and millimeter wave antenna are completed, and the integrated detection antenna of millimeter wave and photoelectric composite is obtained. This composite antenna ensures the maximum detection capability of optical system and millimeter-wave radar and obtains a compact and reasonable integrated structure, which lays a technical foundation for high integration and high performance multi-source detection system.
