Analytical representation of energy spectrum of resonance scattering of meter and decameter radio waves from sea surface

The mechanism of radar signal scattering from the sea is described from the viewpoint of the theories of Bragg’s resonance and electromagnetic wave scattering from statistically irregular surface. It is shown that spectral features of the signal reflected by the sea are determined by the sea water turbulent viscosity and by the sounding signal frequency. The dependence of sea water turbulent viscosity on at-the-surface wind velocity, and that of scattered signal spectral features on weather conditions, are derived.
