—The synthetic aperture radar (SAR) Doppler cen-troid has been used to estimate the scatter line-of-sight radar velocity. In weak to moderate ocean surface current environment, the SAR Doppler centroid is dominated by the directionality and strength of wave-induced ocean surface displacements. In this paper, we show how this sea state signature can be used(More)
Polarization ratio (VV/HH) over ocean surface is processed from Envisat ASAR AP data and compared with existing EM scattering models. The processing of the AP data is based on Level 0 product which enables us to precisely compute the contribution from additive noise separately from each burst. This is of importance in order to estimate a correct(More)
