摘要

本文提出了一种高分辨率星载合成孔径雷达（SAR）数字成像处理的实现方法。利用美国海洋观测卫星SEASAT-A录取的雷达原始数据进行了计算机数字成像

成像规模为距离向2048个距离门

方位向两个合成孔径

其成像面积约为38km×34km

得到了分辨率约为25m×25m高质量的雷达图像

成像结果证明了本文所提方法的正确性。

Abstract

In this paper a realizing method of spaceborne synthetic aperture radar digital imaging is presented.Using SEASAT-SAR radar raw data

computer digital imaging is made.The imaging area is in range 2048 bins and in azimuth two aperture and about 38km×34km.We obtain high resolution radar imagery whose resolution is about 25m×25m.The results show that the imaging method presented in this paper is effective.
