The research on distributed systemís dim target detection and tracking is very important to improve the performance of infrared guard system. When the image background is very intricate, and there are few pels of targets, it is very hard to check the target. An local texture analysis method which is very fit for dim target detection in low signal to noise rate was adopted to realize the detection. In order to satisfy the real-time realization request of dim target detection, a dim target detection system was presented, and it was based on TMS320DM642 which is a high performance digital multimedia DSP chip produced by TI Company. The programís processing speed and pipelining efficiency was improved by optimizing the software program, so the system has a very good software and hardware system structure. Experiments show that the system can detect dim target with 1-3 pixels in clutter background steadily and in real-time.
