MODELING OF SOUND-SCATTERING BY THE SEA-FLOOR

Geoacoustic model of sound scattering by the sea floor is developed, i n which the floor is considered to be irregular layered medium with ra ndom scatterers of two types: the roughness of seabed interfaces and t he volume inhomogeneities (spatial fluctuations of the acoustical para meters). As an example for computer simulation, backscattering by a si lty layer overlaying a sandy half-space has been considered, and the a ngular dependences of scattering coefficient have been calculated.
