In the information warfare,optoelectronic imaging reconnaissance equipment and photoelectric imaging guidance equipment have played an extremely important role in modern combat,and laser suppression interference is an effective means to counteract photoelectric imaging reconnaissance and photoelectric imaging guidance,and it is of great significance to study the effect of laser weapon suppression interference.The article introduces the current status of laser weapons,and classifies and studies the research status of laser suppression interference assessment in two parts:CCD imaging and infrared imaging.The important significance is reviewed briefly,and the current unresolved issues are analyzed,which inspires the follow-up research and provides some reference.
