In recent years, with the increasing improvement of the ranking of precision guided weapons in modern wars, the development and application of infrared imaging guidance technology have attracted more and more attention at home and abroad. However, since the combat missions and battle environment are more and more complicated, the requirement of infrared imaging guidance systems for precision guided weapons is becoming higher and higher. According to the future military development and the current status of infrared imaging guidance technology, it is pointed out that the infrared imaging guidance will develop toward multiband hyperspectral, laser active imaging, multi-mode imaging and low cost infrared precision guidance technologies. The key technologies required in the development of infrared imaging guidance including high performance infrared detector, adaptive imaging anti-jamming, multi-dimensional information fusion and system structure optimization etc are proposed.
