At present, infrared imaging guided missile technology has been widely used in military field, which detects small differences of radiation intensity or frequency between the target and the background, and forms the infrared images of the target and the background to distinguish the target from the background. Based on the analysis of the principle, advantages and disadvantages of infrared imaging guidance, passive jamming technologies for infrared imaging guidance are discussed. And smoke jamming, special material infrared decoy jamming and strong light blinding technologies are imposed.
