In fully polarized SAR (PolSAR) data the returned signal from a target contains all polarizations. More information about this target may be inferred with respect to single-polarization. Distinct polarization separates targets due to its different backscattering responses. https://www.jmannino.com/best-catch-University-of-Miami-The-U-iPhone-14-Plus-Clear-Case-p36265-quick-deal/
