摘要 模糊比的计算是星载SAR系统设计需要考虑的重要方面,多极化系统的模糊比分析与单极化不同,尤其是距离向模糊比与单极化系统有很大的差异。文章主要针对这一问题,给出了多极化模糊比的模型,推导出计算公式,最后给出系统设计的仿真结果以及相应的结论。 The ambiguity is one of the crucial performance parameters in spaceborne SAR system design. The ambiguity of polarimetric SAR is different from that of single polarimetric SAR, especially range ambiguity. The computation of the ambiguity-to-signal ratio in polarimetric SAR is presented. The computer simulation results are presented, and some conclusions are obtained.
