https://www.researchgate.net/publication/279240484_Scattering_Mechanism_Extraction_by_a_Modified_Cloude-Pottier_Decomposition_for_Dual_Polarization_SARIn this paper,It gives the region boundaries of the corrected H/α plane.
However, VV-VH dual polarization is not included.
Sentinel-1 dual polarimetric data includes VV-VH dual-polarization,So what is the H/α plane constructed after H/ α decomposition of vv-vh polarization data？
