This paper proposes an improved four-component scattering power decomposition method with unitary transform of coherency matrix and a suitable volume scattering model for single bounce or double bounce scattering in the polarimetric SAR image analysis. The cross-polarized HV component is created by both single bounce object (such as vegetation) and double bounce structures (such as oriented building blocks). It has been proposed to extend the volume scattering model suited for two physical scattering models. It is shown that vegetation area and oriented urban building area well discriminated compared to those resulting from implementation of the existing four-component scattering power decomposition.
