A study of the RVoG coherent scattering model validity in PolInSAR for forests studies

This work addresses the analysis of the validity of the Random-Volume-over-Ground scattering model for forests studies based on PolInSAR data. The analysis is based on the definition of a Generalized Likelihood Ratio Test that allows to test the model validity for all the pixels of the images and without any external information. Finally, the validity of the RVoG models assumption is tested for data from Tropical and Boreal forests imaged at P- and L-band at different interferometric configurations.
