摘　　要：InSAR与ICEsat测高技术作为极具潜力的两项对地观测技术,各有其特点,利用卫星激光测高数据对星载SAR干涉测量DEM进行倾斜改正具有十分重要的意义,为提取无控制特殊困难地区大范围DEM提供了一种全新的方法。本文介绍了InSAR与ICEsat激光测高两种技术的特点及互补性;分析了利用ICEsat测高数据改正InSAR数据本身难以消除的误差的可行性;并以南极Grove山大范围DEM的提取为例,证实了其优越性。Synthetic aperture radar interferometry （InSAR） and ICEsat satellite altimetry have been proposed as two potential earth observation technique, and both have their characteristics. Study on InSAR DEM Inclination Correction with ICEsat Satellite Altimetry Data has very important significance. This paper introduced the characteristics and complementarities of those two techniques. The feasibility of elimination the errors that InSAR can＇t avoid itself with ICEsat satellite altimetry technique be analyzed. Obtain high precision DEM Grove mountain in antarctica is taken for example to prove the superiority.
