摘要

On the basis of known experimental data, we propose a model for a Doppler spectrum of a horizontally polarized 3-cm microwave signal backscattered from a sea surface at small grazing angles about 100 for wind velocities 3-11 m/s. The model is represented as the superposition of Lorentz and Voight spectral lines with coefficients describing relative energy contributions of different scattering mechanisms as functions of the surface-wind velocity.
