ABSTRACT

An analysis of models of sea radio wave backscattering over the frequency range of 1÷150 GHz has been carried out. The dependences of the normalized radar cross-section on the grazing angle and wind velocity have been considered. The influence of drop-spray fraction on the total radar cross-section and scattered signal fluctuations has been analyzed for the millimeter wave band.
