地形起伏对星载SAR像素定位影响的仿真分析

Analysis of Spaceborne SAR Pixel Location Influenced by Terrain Variation

通过点目标数据仿真,分析地形起伏变化对点目标方位向、距离向位置偏移的影响,并在此基础上,提出利 用斜距变化值和多普勒参数变化值对像素偏移值进行修正的方法,给SAR像素定位问题的研究提供了参考。

This paper discusses the location error of point target induced by terrain variations in azimuths and range direction. The pixel correction algorithms using range and Doppler variation is proposed on the basis of above analysis. The work will provide reference for the radar image location research.
