Caractérisation d'un sol nu à partir de données SAR polarimétriques. Etude multi-fréquentielle et multi-résolutions.

Abstract : This work concerns the characterization of bare soils bio- and geo-physical parameters using multi-frequency and multi-resolution SAR data.

Quantitative relations relating soil roughness and moisture to polarimetric descriptors are established from a scattering model based on the integral equation method. Two multi-frequency surface parameters retrieval algorithms are developed and applied to polarimetric SAR data acquired at the European JRC laboratory.

A rough surface polarimetric response also depends on radar resolution cell size. The relations between SAR resolution and surface polarimetric properties are established by splitting its spectrum into two components. A new scattering model, taking into account resolution effects, is developed and validated using multi-resolution polarimetric data sets.
