| مستخلص: | The main goals proposed for this project were to extend transport theory to range dependent environments and to develop reverberation modeling based on transport theory. The stochastic process emphasized was forward scattering from the sea surface, since it is the most important effect on reverberation modeling that is not being taken into account in reverberation modeling prediction for naval applications. The effect of sea surface forward scattering can affect predicted reverberation levels at mid frequencies by more than 10 dB, and therefore it is one of very few physical effects (if not the only one) not presently being taken into account that can lead to such large reverberation modeling uncertainties. The need to account for surface forward scattering with traditional reverberation modeling approaches readily accessable for naval applications is also being addressed with the development of an effective reflection loss model for the total field, referred to as TOTLOS. The original approach in developing TOTLOS was to base it on the results of Monte Carlo rough surface PE results, but as transport theory became available it became clear that results from it were much more suitable to support TOTLOS development, making it an important secondary goal of the present project.
