DOI: 10.1109/lgrs.2021.3088126
Abstract: In previous publications, it is generally believed that the rotated buildings in built-up areas can induce polarization orientation angles, which cause overestimation of the volume scattering contribution. However, we found that the rotation effect of… read more here.
