Model-based Polarimetric Target Decomposition with Power Redistribution for Urban Areas

Polarimetric decomposition of oriented buildings is challenging due to their variable orientation angles and structures. Both vegetated built-up areas generate the HV component namely cross-polarized scattering, leading an over-estimation volume scattering (OVS). It can cause misinterpretation mechanisms between areas. In this article, we use a pure model designed for completely random describe At same time, new urban revised rate proposed by considering rotated dihedral introducing polarimetric asymmetry (PA), which distinguish different reduce OVS in through power transfer strategy. Then model-based target with redistribution proposed. The performance our method verified RADARSAT-2 C-band UAVSAR L-band data. results show that not only better characterize compared previous methods, but also maintain natural alleviate problem
