Dynamical properties of microwave scattering matrix in radar polarimetry of sea surface

Basic results on the nonstationarity of scattering capillary water waves and the finite extension of the illuminated part of the surface are presented. The main effect leading to fluctuations of the signals scattered by the sea surface at small grazing angles is the modulation effect of sea waves. Using the small perturbation method in conjunction with the Kirchhoff method, relations are obtained for the correlation elements of a scattering matrix measured as the mean specific intensity of the scattering field. The solutions obtained indicate the collective behavior of scattering plots of random-walk sea-surface motion.<>
