Abstract

The glacier is an important factor in climatologic and hydrological investigations, especially in western China. Remote sensing plays an important role for glacier inventorying and monitoring work. SAR systems have an ability to observe the earth's surface, independent of cloud conditions. Particularly, the interferometry and polarization SAR provide a useful tool for glacier investigation, such as extraction of glacial border, measurement of glacier movement and so on. In this paper, we demonstrate the methods and results for the glacier identification integrated intensity of backscattering from Envisat/ASAR images, coherence coefficients of repeat pass interferometry from ASAR and PALSAR, and full polarimetric SAR from PALSAR₀ The movements of several types of glaciers were retrievaled using the SAR interferometry, such as continental glacier, sub-continental glacier and maritime glacier.
