摘要
改进的CS算法和等效斜视的波数域算法是适用于大距离徙动高分辨率星载SAR成像的两种算法。为了给算法的选择提供一些参考 ,本文对两种算法进行了性能分析和比较 ,给出了两种算法在成像精度、算法的适应性和运算量三个方面的特点 ,并利用大量的仿真实验验证了分析结果。
The improved CS algorithm and the equivalent-squint wavenumber domain algorithm are two imaging algorithms applied to high resolution spaceborne SAR with large range cell migration. In order to provide some reference for selection of algorithms,the performance analyzing and comparison are done in this paper and the characteristics of the two algorithms on the imaging precision,the flexibility of algorithms and the calculation quantity are given. A great amount of simulation test validates the analyzing results.
