Abstract: The interaction of radio waves with the sea surface is analyzed. Change of  radio signal, resonant back-scattered by sea surface, as a result of changes in the dielectric constant under the boundary of the ocean-atmosphere, are considered. The quantitative assessment of the  changes in the geometric factor caused by variations in temperature and salinity of sea water are calculated. The analysis is performed for the length of radio waves millimeter, centimeter and decimeter ranges.

Key words: complex dielectric constant, sea surface, Bragg scattering of radio waves, temperature, salinity.
