In order to meet the real?time requirement of ruin?rescue radar,which processes a large number of data by com?plex algorithm,a parallel processing system based on dual?DSP is developed. The master DSP is used to communicate with up?per platform,collect data,detect body?moving signals and preprocess static targets. The slave DSP is used to detect static tar?gets. The data communication between the two DSPs is relized through HPI interface of the slave DSP. The problem that the sin?gle DSP can’t meet the real?time algorithm was solved with this method. The hardware design,software processing flow and soft?ware program optimization of the processing system are described.
