Transport Theory for Propagation and Reverberation
Abstract
A three-year period of research is proposed for extending the development of transport theory with particular emphasis on modeling" the effects of sea surface forward scattering on the vertical angular distribution of ambient noise, where transport theory accounts for the effects of forward scattering from rough boundaries. The proposed approach is based on expanding the acousticfield in modes, and therefore would most readily apply at mid-frequencies and below, and in relatively shallow water environments such as on the continental shelf. Important advantages of transport theory as proposed are its accuracy, computation speed, and the ability to account for multiple forward scattering from rough boundaries. A key goal of the proposed research is to extend transport theory to obtain the vertical coherence, a different second moment from theaverage intensity that has been employed to date. This work will have" application to including the effects of surface forward scattering on modeling the vertical distribution of ambient noise.
