Coherent Reflection Of Acoustic Plane Wave From Rough Interfaces In A Stratified Random Fluid Medium, Jin-Yuan Liu, Shiahn-Wern Shyue, Chen-Fen Huang

Journal of Marine Science and Technology

Coherent reflection of an acoustic plane wave from rough interfaces in a horizontally-stratified medium, within which the sound-speed distribution subject to a small and random perturbation, is considered in this paper. The general formulation based upon the theory for rough-interface scattering in a stratified medium, in conjunction with that for random medium is derived. The Green’s function for a random medium bounded by two surfaces, which serves as generic solution of the problem, is obtained. The formulation is then applied to a simplified seabed environment to study the effects of surface roughness and medium inhomogenieties on the coherent reflection. The …
