Abstract

The potential limitation of a stochastic volume scatter on large aperture, ocean acoustic systems has resulted in the development of propagation and scattering models formulated in terms of two-point coherence functions. By incorporating two additional features, these models can be regarded as generalizations of those originally developed for a similar application, but which involved electromagnetic signals in the atmosphere. One feature is an inhomogeneous background medium, resulting in an acoustic channel, which is a necessary input in discussing long-range propagation. The second is an extreme anisotropy which characterizes the scattering mechanism operative in the ocean. The models are discussed in physical terms; and the differences effected by the above-described factors are emphasized.
