Abstract :
The authors introduce a new model for the inversion of surface roughness and moisture from polarimetric SAR data, based on the eigenvalues and eigenvectors of the coherency matrix. They present how three parameters, namely the polarimetric entropy, the anisotropy and the alpha angle can be used in order to decouple roughness from moisture content offering the possibility of a straightforward inversion of these parameters
