Abstract: The impact sea surface waves longer than the resonant components, on the backscatter of radio waves of millimeter range is analyzed. The situation when long waves in relation to the resonant components are waves, that length more than 2 cm are considered. The physical mechanisms that determine impact of long, compared with the resonant components of the waves on the magnitude of the normalized backscattering cross section are discussed. Numerical estimates of the change in the back scattering cross-section for sensing horizontal and vertical polarization, due to the presence of long waves are obtained.

Key words: sea surface, Bragg scattering of radio waves, surface wave, the local slopes.
