摘要: 针对合成孔径雷达(synthetic aperture radar,SAR)实时成像处理中数据量大、数据吞吐率高、成像算法实现复杂等特点,提出了一种适合于SAR实时成像处理的共享存储器的分布式耦合系统架构,设计了高分辨率SAR实时成像中大IO带宽、高处理能力、大存储容量等解决方案.给出了详细的硬件实现以及成像处理平台的测试结果,并用实测雷达回波数据进行了实时成像验证.

Abstract: According to the common characters in the process of real-time imaging of the synthetic aperture radar(SAR),such as huge data volume,high IO bandwidth and complex algorithm,a distributed-system architecture based on the shared memory is proposed.The schemes of high IO bandwidth,high performance and large memory are introduced.The implementation of hardware is described in detail and the test results are shown.Finally,the utility of the architecture is demonstrated with the measured echo data.
