三孔径SAR-MTI系统的性能分析

The Performance Analysis of a Three-Port Interferometer SAR-MTI

具体分析了用于检测和定位运动目标的三端口SAR -MTI系统工作原理及性能。着重讨论了各种误差对检测和定位运动目标的影响 ,并对假设的雷达系统进行了计算机仿真。结果表明 ,在存在各种系统误差的条件下 ,系统仍具有良好的性能。由于是开环处理 ,这种系统具有较强的环境适应能力 ,同时处理所需的计算量和硬件设备量也不大 ,因此这种方法容易在工程上实现。

The principle and performance of a three port interferometer SAR-MTI for detecting and relocating moving targets are analyzed. The emphasis is placed on the influence of various errors on the performance of detection and relocation. The computer simulation is carried out for a assumed radar system and the results show that the system still has good performance under different errors. The calculation and hardware for processing is not large, therefor the method is easy to be realized in the engineering.\;
