Description: 双极化SAR用一个小天线作为单个辐射单元，将此单元沿一直线不断移动，在不同位置上接收同一地物的回波信号并进行相关解调压缩处理的侧视雷达。-The Defence R&D Canada–Ottawa (DRDC Ottawa) is participating in a joint
experiment with the Air Force Research Laboratory (AFRL) in Rome, New York
under TTRDP. The objective of this study is to understand bistatic radar and bistatic clutter statistics, and to investigate processing methods with the ultimate aim of detecting airborne targets. As part of this study SAR processing techniques are developed for bistatic SAR data.
The data set used to test the processor in this study were acquired in Rome, NY during the trial dated 28 January 2002. The data are examined for saturation, integrity,spectral properties and phase stability. The bistatic SAR processor is coded in Matlab using time-domain azimuth compression and bistatic SAR images are produced.
