摘要

This paper proposes an advanced method to improve thernthree-component decomposition so that it can be appliedrnto azimuthally inclined objects such as skew-orientedrnbuildings. We already have a similar technique which isrnthe four-component decomposition with deorientation.rnBoth of the techniques employ the rotation of scatteringrnmatrices. However, in the proposed method,rnpolarisation orientation (PO) angles are embedded to thernmodels for surface scattering and double-bounce,rnrespectively. It is expected that overestimate of volumernscattering component is suppressed by embedding POrnangles for surface scattering and double-bounce,rnrespectively, if PO angles are different between the tworncomponents. Decomposition results were compared tornthat of the four-component decomposition withrndeorientation. It was confirmed that the volumernscattering was not much different between two methods,rnwhile the ratio between surface scattering and doublebouncernwere different. The proposed method seems tornprovide us a more reasonable result.
