An embedded infrared target processing system based on Automatic-Target-Recognition (ATR) technology is studied. It can be used to implement the automatic recognition and tracking of the dynamic infrared target. According to the requirements in function, an embedded processing system which includes an infrared signal collection processing module, an automatic target recognition and tracking module and an embedded control module is desinged. The system can process the dynamic target at high speed in real time and has a user-frendly interface. It is of active significance to the increase of target recogniton speed and the miniaturization of the system. The specific implementation of the software and hardware for each functional module of the system is presented emphatically.
