摘　　要：雷达影像以其全天候、全天时、穿透力强的工作能力,成为当前摄影测量与遥感领域的研究热点,近年来机载SAR系统在国内外得到快速发展和应用。本文介绍了高分辨率多极化机载SAR数据的特点,论述了SAR影像的正射纠正,分析了不同地表要素在机载SAR影像中的成像特点和解译方法,并与光学影像作了对比,得出了基于SAR影像地表要素解译的几点看法。Radar imagery becomes the study hotspot in the field of photogrammetry and remote sensing due to its all - weather, all - time and powerful penetration working capability. The airborne SAR system has made rapid development and has wide application at home and abroad. This paper introduces the features of high resolution and multi - polarization airborne SAR, discusses the ortho - rectification of SAR images, and analyzes the imaging features and interpretation methods of different surface elements of airborne SAR images, compares it with optical images, and draws some conclusions on surface elements interpretation based on SAR imagery.
