Abstract:The development and current situation of laser guidance technology areintroduced, The advantages and disadvantages of laser guidance are summarized, The laserjamming technology is analyzed and researched emphatically. It is pointed out that with thedevelopment of anti-jamming technology of laser guidance weapon, single jamming mode cannot meet the needs of modern electronic warfare, information warfare and intelligentwarfare, Therefore. composite iamming should be used to improve the success rate of laseguidance weapon.
