Abstract :
In this paper we introduce a new ratio of polarimetric scattering coefficients that we suggest is sensitive to surface moisture content and insensitive to roughness variations. The parameter is first derived from the extended Bragg surface model and then validated using wide band chamber measurements of surface backscatter collected at the European Microwave Scattering Laboratory (EMSL).
