Abstract. This paper provides a brief overview of sea waves and examines various models of sea surface spectrum. A model of sea surface variation is presented, and wave scattering problem from rough sea surface successive realizations using the integral equation method is considered. Spectra of a VHF signal scattered by the sea are obtained for vertical and horizontal polarization of the incident field. It is shown that at wind speeds of 3–5 m/s, the scattered signal spectra correspond to the resonant (Bragg) scattering theory; with increasing sea waves there is a gradual transition from resonant to non-resonant backscattering.

Key words: sea surface, sea-spectrum model, Bragg scattering, integral equation method, backscattering from the sea.

Financing: The work was carried out with the support of the Ministry of Science and Higher Education of the Russian Federation (project no. FZGM-2025-0002.
