A multiple-component polarimetric decomposition method with refined volume scattering models

In this letter, a multiple-component polarimetric decomposition method with refined volume scattering models is proposed. In the proposed algorithm, the volume scattering models under the assumption of reflection symmetry are refined by employing the orientation angles. In addition, wire scattering component is introduced to overcome the overestimation of volume scattering. ESAR data collected by the German Aerospace Center (DLR) are used to evaluate the performance of the method. The experimental results demonstrate that the proposed method can be used to characterize the scattering mechanisms of various terrain types and the overestimation of volume scattering can be effectively overcome.
