摘要

空载合成孔径雷达（ＳＡＲ）是一种现代高分辨率侧视成象雷达，它应用合成孔径技术、脉冲压缩技术和数字信息处理技术，获得方位向和距离向的高分辨率。本文将对空载ＳＡＲ的现状及发展趋势进行综述，并主要讨论ＳＡＲ的有关技术，涉及星载ＳＡＲ工作模式和体制，雷达数字图象的信息获取与成象处理等，最后，给出了ＳＥＡＳＡＴ－Ａ卫星ＳＡＲ数字成象结果。

Abstract

Spaceborne synthetic aperture radar（SAR） is a kind of modern high resolution sidelooking imaging radar. Making use of the techniques of the synthetic aperture

pulse compression and digital information processing

it obtains high resolution in azimuth direction and in range direction. In this paper

the present situation and development trend of spaceborne SAR are summarized. The main techniques of SAR are disscussed

which include spaceborns SAR patterns and systems

and information processing and imaging processing of SAR digital image. Finally

the imaging results using SEASAT-A satellite SAR raw data are provided.
