Evaluation du potentiel de la technique PolInSAR pour l'estimation des paramètres physiques de la végétation en conditions satellitaires

Abstract : The goal of this work has been the evaluation of PolInSAR technique potential for the extraction of forest physical parameters and the transposition of such analysis to spatial conditions.

Previous works have shown that PolInSAR technique presents a good potential for tree height inversion, which can be linked to the above ground biomass through allometric relation, using L-band data. The first part of this work has consisted in the inversion procedure adaptation to extreme frequencies of the spectra which is generally used for natural surfaces investigation, X- and P-band, using data acquired over pine forests by RAMSES airborne system.

Then, influence of the most variable system parameters from airborne to spaceborne conditions, as resolution and Signal-to-Noise ratio, is evaluated on the inversion robustness and accuracy at X-, L- and P-bands, in order to determine its limitations in spaceborne conditions.
