In this work the potential of using the interferometric coherence at different polarisations over surface scat- terers in order to extract information about surface parameters is investigated. For the first time the sensitivity of the indi- vidual coherence contributions to surface roughness and moisture conditions is discussed and simulated using a novel hy- brid polarimetric surface scattering model. The model itself consists of two components, a coherent part obtained from the extended Bragg model and an incoherent part obtained from the integral equation model. Finally, experimental airborne SAR data are used to validate the modeled elements of the Pauli scattering vector.
