Abstract
It is noted that in the absence of random inhomogeneities in the range of small slip angles there is a minimum of intensity It is conditioned by the minimum in the angular distribution of the radiation intensity of separate sources. At the presence of random inhomogeneities takes place the energy pumping-over in the range of small slip angles. The vertical directionality of the noise field produced by surface sources is considered in the framework of the model of a shallow constant-depth sea. Intensity expressions are obtained with allowance for the scattering by anisotropic random inhomogeneities. For a constant-sound-velocity channel analytical angular intensity relations are derived.
