Model-Based Interpretation of PolSAR Data for the Characterization of Glacier Zones in Greenland ...
Different approaches have been proposed in recent years to map glacier zones using Synthetic Aperture Radar (SAR). Most of them rely on empirical or statistical approaches for the interpretation of backscatter intensity measurements and their seasonal variations related to the melting regime of the...
