Scattering Mechanism Extraction by a Modified Cloude-Pottier Decomposition for Dual Polarization SAR

摘要: Dual polarization is a typical operational mode of polarimetric synthetic aperture radar (SAR). However, few studies have considered the scattering mechanism extraction dual-polarization SARs. A modified Cloude-Pottier decomposition proposed to investigate performance It theoretically demonstrated that only HH-VV SAR can discriminate three canonical mechanisms from an isotropic surface, horizontal dipole, and dihedral. Various experiments are conducted using 21 scenes real datasets acquired by AIRSAR, Convair-580 SAR, EMISAR, E-SAR, Pi-SAR, RADARSAT-2. Division H-α plane experimentally obtained. The lack cross-polarization induces diffusion their overlap in plane. for extracting acceptable. Thus, suitable alternative full-polarization certain cases. Meanwhile, other two SARs badly degraded due co-polarization. Therefore, HH-HV HV-VV cannot effectively extract
