摘　　要：介绍我国机载干涉SAR系统及测绘应用概况,介绍机载干涉SAR生成DEM、SAR正射校正、地形引起的SAR后向散射畸变校正、机载SAR图像解译、雷达图像与光学影像的融合、雷达"空中三角测量"等关键技术研究进展。最后,介绍机载干涉SAR系统在泰山试验区的测绘制图实验情况。This paper analyzes the application status of airborne SAR interferometry system, and briefs on the general situation of airborne SAR interferometry system and its mapping application. In this paper, some core technologies of SAR mapping such as airborne SAR interferometry extracting DEM, SAR orthoreetification, backscatter distortion rectification caused by topography, airborne SAR image interpretation, SAR and optical image fusion, SAR aerotriangulation, and software development, are also studied. Finally, the mapping application of this SAR system in Mountain Tai is put forward.
