The Spaceborne Image Radar (SIR-C) onboard the space shuttle Endeavor acquired interferometric synthetic aperture radar (INSAR) data over Mt Kunlun
NW China
during its second flight In this paper
DEM acquisition of test site using SIR-C INSAR data was demonstrated The main procedure included coregistration of data
remove of flat terrain effect and phase unwrapping using DCT technique The results show more details than the existing topographic map The precise correction and analysis have to be done in the further work
