    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.

    InSAR(Synthetic Aperture Radar Interferometry) is a new technology for achieving Digital Elevation Model(DEM).The paper introduces the basic flow of achieving DEM with InSAR technology and describes the theoretical method of phase unwrapping,at the same time the method and principle of obtaining ground control points among baseline evaluation processing are brought forward.Then,a DEM of the western mountain area was obtained,which also is compared and analyzed with SRTM-DEM.The reasons for their existence are summarized at last.
