Abstract

Synthetic aperture radar interferometry(InSAR) is a new technology to build the digital elevation model(DEM) and detect the tiny changes in the surface.In the paper,we summarize the development of the InSAR,introduce the basic theory of InSAR,and then present the procedure of building DEM through InSAR by using the data about Hoh Sai Lake on Tibetan plateau.At last,we analysis the results of the DEM obtained by InSAR.
