Abstract :
Polarimetric SAR data acquired during the first and second SIR-C/X SAR mission over bare soils located at Les Landes (France) and Matera (Italy) test areas, are exploited in order to investigate the antenna polarization effect on polarimetric surface roughness discriminators. Among quantities under consideration, the copolarized correlation coefficient in circular polarization shows the best sensitivity to surface roughness
