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.
