The Glacier Identification using SAR Interfermetric and Polarimetric Information in Qinghai-Tibetan Plateau

For climatological and hydrological investigations, the areas covered by glacier and their spatial variability are important parameters, particularly in Qinghai-Tibetan Plateau. A interferometric SAR technique not only can produce a high-resolution digital elevation models but also can identify the surface object with coherence coefficients. This property of SAR polarimetry is particularly useful in classification. In this paper we analyze to demonstrate the method and result for the glacier identification integrated intensity of backscattering from Envisat/ASAR images, coherence coefficients of repeat pass interferometry from ASAR and ALOS/PalSAR, and full polarimetric SAR from PalSAR.
