PC-Based Propagation and Sonar Prediction Models

Abstract

Executive Summary: The use of numerical models in ocean acoustics has proliferated over the past two decades, trailing closely advances in computer technology. Earlier models were all ray-based and ran quickly on available main-frame computers. Next came the more accurate but computer-intensive wave models based on normal modes or the parabolic equation (PE) approach. Today these models are the preferred prediction tools in the scientific community, and are also being introduced into operational use. Wave theory models are applied primarily to low-frequency problems, but they still require powerful workstations to provide answers in 'real' time.
