The system of infrared imaging fuze based on imaging seeker information can get a series of dynamic infrared images of target from the whole to a part and realize forward looking detection. The recognition of aircraft status is of great significance to fix aimpoint by imaging fuze. The moving characteristics of aircraft in high speed encounter is analyzed and the rotating status of target image on image plane and the position of aircraft nose are obtained through genetic algorithm. The pitching status of aircraft is obtained by utilizing the distance information provided by measurement device, the length of target image and the system parameter of infrared detector. Finally, the recognition of aircraft status is realized by use of the invariability of azimuth angle and pitch angle of target axis during encounter of missile and target.
