摘　　要：雷达脉内分析一般采用中频数据,数据量大,处理算法复杂,运算量大,实时性差。基于多节点高性能多核CPU信号处理平台,提出了一种基于消息传递接口(MPI)+开放式多处理(OpenMP)的雷达信号脉内分析技术,综合利用了MPI跨节点并行以及OpenMP节点内并行的特点,实现了雷达信号脉内分析的高性能脉冲级并行处理。在基于IntelXeon2640构建的多节点集群系统上的测试结果表明,该方法显著的提高了脉内分析的处理速度。Radar intra-pulse analysis generally adopts intermediate frequency data,which has a large amount of data,complex processing algorithms,a large amount of computation and poor real-time performance.Based on the multi-node high-performance multi-core CPU signal processing plat-form,this paper proposes an intra-pulse analysis technology of radar signal based on message pass-ing interface(MPI)+open multiprocessing(OpenMP),which comprehensively utilizes the charac-teristics of MPI cross-node parallelism and OpenMP intra-node parallelism to realize high-perform-ance pulse-level parallel processing of radar signal intra-pulse analysis.The test results on a multi-node cluster system built on Intel Xeon 2640 show that this method significantly improves the pro-cessing speed of intra-pulse analysis.
