Abstract
The authors present polarimetric radar measurements at 225 GHz which demonstrate that the normalized Mueller matrix may be approximated in terms of a single parameter, The depolarization ratio, defined as the ratio of cross- to copolarized normalized radar cross-sections, is shown to accurately predict backscatter from vegetation (trees and grass), and scattering from terrain at low incidence angles (snowcover and sand).<>
