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。
The Spaceborne Synthetic Aperture Radar (SAR) is a modern high-resolution side-view imaging radar that uses synthetic aperture techniques, pulse compression techniques and digital information processing techniques to achieve azimuth and distance resolution. This article will review the current status and development trend of the no-load SAR, and mainly discuss the related technologies of SAR, including the working mode and system of the spaceborne SAR, the information acquisition and image processing of the radar digital image, etc. Finally, -A satellite SAR digital imaging results.
