Abstract :
In this paper we relate the eigenvector formulation of polarimetric backscatter to published coherence and amplitude ratio approaches to surface roughness measurement. Several important relationships appear and the formulation leads us to propose a new model for the analysis of surface data which promises to provide separable roughness and moisture parameters
