Wave Propagation in Random Media.

Abstract

Sound waves, propagating through the ocean, may be accompanied by surface, bottom and volume reverberation. One of the causes for the volume scattering is the thermal microstructure of the medium. Its effect on wave propagation is discussed in this report, from a theoretical point of view. Sound frequencies from the diffraction domain up into the band where geometrical optics are valid, have been considered. The medium is assumed to be unbounded, homogeneous, stationary and anisotropic, with weak fluctuations in the index of refraction. (Author Modified Abstract)
