In response to the increasingly complex battlefield combat environment, the capability of anti-interference becomes a very important index. Infrared imaging guidance weapon is widely used because of it high hit ratio ,high efficiency cost ratio and strong anti-jamming ability.With the explosion of tracking algorithms of infrared imaging seeker, and the single evaluation method based on weapon strike accuracy can no longer fully reflect the anti-jamming ability of infrared imaging seeker. This paper constructs a life-cycle effectiveness evaluation system based on the three dimensions of target recognition, image characteristics and tracking accuracy. Based on building simulation countermeasure scenarios, the infrared imaging seeker anti-interference performance are used to simulate. The simulation result showed that the effectiveness evaluation system can accurately evaluate infrared imaging seeker performance.
