The Dual Polarization Entropy/Alpha Decomposition: A PALSAR Case Study

In this paper we develop a dual polarized version of the entropy/alpha decomposition method. We first develop the basic algorithms and then apply them to theoretical models of surface and volume scattering to demonstrate the potential for discrimination, classification and parameter estimation. We then apply the formalism to d ual polarized data from the ALOS/PALSAR system operating in PLR and FBD modes to illustrate application to forest classification, urban scattering characterization and point target signature analysis for ship classification.
