Multipath and Attenuation Studies in the Deep Ocean.
Abstract
Analysis methods are developed for studying the various ray paths that connect widely separated acoustic sources and receivers in the ocean. For an arbitrary velocity profile and for a source and receiver located at arbitrary points in the medium, it is shown that acoustic propagation can be discussed in terms of one of four possible cases. For each case, a set of curves, called an angle range plot, can be developed and used in the interpretation of many features of the acoustic propagation. These features include the presence of caustics and the number and intensity of received arrivals from a single pulsed signal. (Author)
