A Perspective on Bottom Reflectivity and Backscattering
A review of available data and description of observed effects permit an assessment of progress made since the 1970 SACLANT Conference on this same topic. Physical models have been developed and refined which can both explain the observations and serve as a basis for predictions. Examples will be presented which contrast values determined from the physical models with measured data in order to identify problem areas and to recommend directions for future efforts.
