Optical image is rich in spectral information, while SAR instrument can work in both day and night and obtain images through fog
and clouds. Combination of these two types of complementary images sh...
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...
