The paper is aimed at the comparative study of the wind-induced effects on the large horizontal array gain in shallow-water channels for several signal processing techniques, optimal ones included. Computer simulation is performed for some environmental conditions typical for the Barents Sea in the winter season and the Pierson-Moskowitz model for developed wind waves. The results obtained exhibit considerable effects of multiply sound scattering on the array gain and its essential dependence on the array size, propagation distance and wind speed.
