A multimode, small, Wide-Field-of-View, lightweight, low-cost photodetector is the key to develop the next generation precision-guided munitions. As one of the important representatives, the Wide-Field-of-View photoelectric detection system based on artificial compound eye has been highly valued by the U.S. Air Force. Through a number of innovative research projects, the U.S. military expects to develop a multi-aperture Wide-Field-of-View artificial compound eye photodetector, which can be used for autonomous guided munitions and strengthen the environmental perception, penetration and confrontation ability, and combat effectiveness of the next generation of precision guided munitions. The development requirements of precision guided munitions, as well as the structure and characteristics of compound eye, were briefly described. The application expectations and assumptions of artificial compound eye in precision-guided weapons in the U.S. military were introduced. The advantages of artificial compound eye in urban combat weapons and equipment were briefly discussed. The progress of foreign artificial compound eye in infrared precision-guided munitions was discussed, as well as the research and development process. The application progress of foreign artificial compound eye in semi-active laser-guided munitions was described. Finally, the research suggestions on the application of artificial compound eye in precision-guided weapons and equipment were given.
