摘要
对适用于星载SAR斜视情况下的距离-多普勒(R-D)算法进行了详细系统的理论分析,并对比了两种R-D算法的不同.分析了时域和频域两种距离徙动校正方法,证明了二次距离压缩的产生原因和实现途径.最后给出了成像结果,并提出了一些建议.
The R-D algorithm used in squint mode spaceborne SAR is analyzed carefully in theory, and the difference between the two R-D algorithms is also discussed and compared. The methods for the correction of range migration in time and frequency are analyzed particularly. The reason for SRC and the way to complete SRC are given. Finally, the images of R-D algorithm are given, and some suggestions are proposed.
