The brewster effect on polarimetric information
Abstract
When the incidence angle is equal or about the Brewster's angle, a lossy medium favors the transmission of VV polarization. As a result, there may be a strong difference between the co-polarization components of the reflected waves. For a dihedral-type scattering mechanism, this effect is enhanced and occurs for a wider range of incidence angles. This situation - typically present in urban areas - may induce significant changes in the polarimetric signatures.
