Modelling of sound scattering by the sea floor

Abstract
Geoacoustic model of sound scattering by the sea floor is developed, in which the floor is considered to be irregular layered medium with random scatterers of two types : the roughness of seabed interfaces and the volume inhomogeneities (spatial fluctuations of the acoustical parameters). As an example for computer simulation, backscattering by a silty layer overlaying a sandy half-space has been considered, and the angular dependences of scattering coefficient have been calculated.
