Abstract :
This paper introduces a qualitative characterization of dry snow scattering behaviour in Alpine areas. An electromagnetic scattering model is developed, based on the vector radiative transfer equation, to simulate the fully polarimetric response of a snow cover. Multi-temporal and multi-frequency polarimetric SAR data acquired over Alpine test sites are analyzed by comparing polarimetric indicators to simulated ones with various sets of snow cover characteristics.
