Scattering of Laser Beam by Rough Sea Surface

The scattering of the laser beam by the rough sea surface is considered. Analytical expressions for average received power are obtained at normal distribution of heights and slopes of sea surface for two cases: the direction on the receiver is either close to the direction of mirror reflection or strongly differs from it. The received laser echo forms for the two cases vary essentially and are defined by parameters of the source, receiver, scheme of sounding and wind speed. The analytical formulae obtained for the received average power conform well to results of numerical calculations.
