A Three Layer Fluid Model for Estimating Ocean Bottom Reflectivity at Various Frequencies.

Abstract

The adoption of the bottom bounce mode of underwater sound propagation for sonar applications has made a consideration of ocean bottom sound reflectivity essential. The following discussion is an attempt to: (1) Relate observed ocean bottom physical and acoustic properties, and (2) present a better theoretical approach for comparison with existing measurements than those previously employed.
