Ocean-Basin Reverberation From Large Underwater Explosions: Part 1: Source-Level and Propagation-Loss Modelling

Abstract

Predicting the reverberant returns from ocean basin reflectors requires describing acoustic source levels for large, conventional underwater explosions, defining the two way propagation loss and signal spreading from the source to the reflector and then to the receiver, and modelling the reflection or scattering process at reflectors such as basin walls. These components must then be put in the framework of a model, or computer program, that relates them properly. This paper will discuss the first two aspects of the problem, namely, the source levels and propagation loss modelling.
