Initial Phase of a Study of Bottom Interaction of Low Frequency Underwater Sound.

摘要

Bottom interaction is recognized as an important and only partially understood component of low frequency underwater sound propagation. Several phases of this complex problem hanve been investigated during the first year of a planning multiple year study. Several phases of this complex problem have been investigated during the first year of a planned multiple year study. This report describes several aspects of the study including sensitivity of propagation loss to bottom loss variations, sensitivity of bottom loss to variations in ocean bottom physical parameters, bottom roughness effects, and propagation over a sloping bottom.
