An analysis of sea backscattering models in frequency band of 1ё150 GHz is carried out. The dependences of the sea surface normalized radar cross-section (RCS) on the grazing angle and wind velocity are discussed. The influence of drop-spray fraction on the total RCS and scattering signal fluctuations for the millimeter band of radio waves is analyzed.
