A Literature Survey of Reverberation Modeling: With Emphasis on Bellhop Compatibility for Operational Applications

Abstract

Recent publications of reverberation and scattering strength modeling are reviewed. Emphasis is placed on investigating operationally oriented models (as opposed to research oriented) that may be compatible with the Bellhop propagation model for use within the Environment Modeling Manager (EMM). Special attention is given to the research of Dr. Dale Ellis including his normal mode reverberation model, his clutter model approach, and his scattering strength model. Recommendations are made to consider adding the Ellis normal mode model and the Harrison closed form expressions to the Environment Modeling Manager to compliment Bellhop. It is recommended that a range of bottom scattering strength models be implemented to provide a choice of grazing angle dependences. It is recommended that the Gauss surface scattering strength model be investigated to possibly replace the Ogden-Erskine model. It is also recommended that the Ainslie angle/decay rate relationship be examined to possibly provide the experimental evidence for choosing one scattering strength kernel over another at each operational site.
