在ＳＰＯＴＬＩＧＨＴＳＡＲ的各种成像算法中，聚焦的准确性是影响ＳＡＲ成像质量的关键所在。在建立ＳＰＯＴＬＩＧＨＴＳＡＲ数据搜集及成像处理的数学模型基础上，比较了两种ＳＰＯＴＬＩＧＨＴＳＡＲ成像算法ＰＦＡ和ＲＭＡ的性能，并通过计算机仿真进行了分析和比较。

[Abstract]
In all algorithms for synthetic aperture radar (SAR) imaging, the focusing quality is the key to the SAR imaging. Based on the mathematical model for collecting and processing SPOTLIGHT SAR data, the performance of two algorithms for SPOTLIGHT SAR imaging (polar format algorithm, PFA; range migration algorithm, RMA) is compared and analyzed with results of computer simulation.
