Acoustic propagation models as viewed by the sonar systems designer

Abstract

The purpose of this paper is to consider the efforts performed in the development of ray acoustic propagation analyses from the viewpoint of advanced sonar system design. In particular, those parameters required of such analyses for the enhancement of sonar system design and performance are identified and elaborated upon. A simple ray acoustic shallow water propagation model is used as a vehicle for identifying and relating to a number of areas in which propagation results may be utilized to significantly improve operational sonar system effectiveness. In the development of these examples, the spatial distribution of the acoustic energy together with fluctuations in the received signal energy receive prime consideration. Expanding upon this simple basis, a sonar design concept is developed by analytically incorporating propagation features that can be provided by suitable models.
