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.
