Transport Theory for Propagation and Reverberation
Abstract
The research will extend the development of transport theory for propagation and reverberation, which accounts for the effects of forward scattering from rough boundaries. Predictions will be comparex with data from the TREX13 experiment. A three-year period of research is proposed for extending the development of transport theory for propagation and reverberation, where transport theory accounts for the effects of forward scattering from rough boundaries. A key goal of the proposed work is to publish in detail the progress made to date on transport theory development. A second goal is to pursue the development of transport theory for general 2-D wave spectra, needed for data/model comparisons. A third goal will be to improve data-model comparisons with TREX13 results for propagation and reverberation to further verify transport theory predictions. A fourth goal is to use transport theory results to support the development of the TOTLOS model (an effective reflection loss for the total field) that will allow effects of sea surface forward scattering to be incorporated into standard raybased, mode-based, or energy flux propagation and reverberation models. The proposed approach is based on expanding the acoustic field 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 (or internal waves).
