摘　　要：针对基于CPCI或VME构建的雷达信号处理系统数传和处理能力的瓶颈,提出了一种以TI公司多核DSP TMS320C667x为核心处理器、基于VPX架构的高端高速雷达实时信号处理系统,介绍了系统的软硬件架构设计、电气结构设计、背板拓扑结构设计以及在雷达SAR成像处理模式、单脉冲处理模式的应用软件设计。工程应用中的测试结果表明,该系统具有比传统信号处理系统更高的处理性能和与高性能相匹配的高速数传网络,应用前景广阔。For radar processing systems based on CPCI or VME,the data transmission and processing capability is a bottleneck.To address this issue,the design of a highly real-time processor based on multi-core DSP TMS320C667 x from TI and VPX is presented,the design of software,hardware,electric structure and backplane topological structure is introduced,and the applications in SAR imaging and monopulse processing are proposed. The testing results in engineering application shown that this system has a better processing performance than traditional signal processor and a high-speed data transmission network matching with its high performance,and it has a good prospect of application.
