The study to extract DEM from stereo SAR

LI Yongrong ①,ZHANG Jixian ①,HUANG Guoman ①,LIU Mingjun ②(①Chinese Academy of Surveying and Mapping, Beijing 100039 China ②Wuhan University,Wuhan 430079,China)  
The SAR loaded in satellite get images by the way of microwave. SAR has the advantage that optical images method can not to compare with, because microwave can pass through atmosphere containing cloud、snow、rain、mist and so on. Now people are actively exploring how to make good use of SAR date in the field of survey and mapping. Considering SAR's stable motion and highly relative relations in a short time, this article mainly explains characteristics of Radar images and howto extract DEM from stereo SAR images,and then gives a detail explanation how to perform it.
