摘要：We investigated the potential of fully polarimetric data in X-band to discriminate the principal surface typespresentin a study site near Avignon in France: bare soils, agricultural fields, orchards (various fruits), forest, buildings, residential houses, and roads. Decomposition and analysis techniques have been applied to a data set acquired by the ONERA airborne RAMSES SAR. The discrimination potential of various polarimetric parameters (entropy, α-angle, anisotropy) have been discussed. Results show that X-band provides some discrimination capability. The polarimetric parameters, entropy and α-angle, show clearly that these classes' signatures are grouped in five clusters corresponding to physical scattering characteristics. The introduction of the parameter anisotropy does not improve our ability to distinguish between different classes whose clusters are in the same entropy/α-angle zone. We observe a very weak correlation between the signal radar and the surface roughness over bare soils
