为了满足废墟搜救雷达数据量大、算法复杂、实时化要求高等特点，采用一种双DSP并行处理系统，主DSP负责与上位机通信、数据采集、体动信号检测和静目标预处理，从DSP负责静目标的检测，通过从DSP的HPI接口实现与主DSP之间的数据通信，解决了单DSP难以满足算法实时化的问题，阐述了处理系统的硬件设计、软件处理流程与软件程序优化方法。%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.
