The implementation of an improve infrared dim-small target track before detect based on DSP

For detecting and tracking the infrared dim-small target with the low SNR, the particle filter algorithm is applied to the problem of infrared dim-small target´s tracking before detection in this paper. The infrared dim-small target´s tracking before detection based on the full view sampling´s particle filter algorithm is proposed. And the hardware system is composed of an infrared imager, the ICETEK-DM642-PCI development board and the monitor. The hardware system is configured by using DSPIBIOS which is a real-time operating system. The experimental results show that the system achieves better detection and tracking´s effect than the traditional methods.
