| Abstract(in English) | In this report, we will introduce a new model-based scattering power decomposition method for polarimetric SAR (POLSAR) data analysis. The observed POLSAR coherency matrix is assumed to be the combined contribution of volume scattering and two single-scatterers. Under this assumption, we first show that for a given volume scattering model, its corresponding power can be uniquely determined through solving a generalized eigendecomposition problem. After that, two different approaches are proposed for discriminating the remaining matrices. One is based on eigendecomposition and the other is based on optimal model fitting. Both methods can properly resolve the surface and double-bounce scattering ambiguity. The proposed scattering power decomposition technique enjoys several advantages, notably a systematic (rather than ad-hoc) prevention of negative powers as well as full utilization of polarimetric parameters. |
