Infrared precision-guided weapons,typified by man-portable air defence systems(MANPADS),pose a sig-nificant threat to military and civilian aircraft.At present,the most effective countermeasure against heat-seeking guided weapon is the directional infrared jamming system,which uses infrared-band lasers as the light source.This paper mainly introduces how Raytheon Company develops a new generation of directed infrared countermeasure system based on the existing AIM-9X seeker technology.The system has many advantages,such as high efficiency,reliabili-ty,compactness,light weight and low price,and through the expansion of the functions,it can easily cope with the threat of missiles in various wavelength bands from ultraviolet to mid-infrared.
