Development of a Comprehensive Hydroacoustic Coverage Assessment Model.

Abstract

A model for predicting the detection and localization performance of hydroacoustic monitoring networks has been developed. The model accounts for major factors affecting global-scale acoustic propagation in the ocean, such as horizontal refraction from bathymetric features and horizontal changes in sound speed, travel time variability due to spatial and temporal fluctuations in the ocean, and detailed characteristics of the source. In this report, a summary description of the component submodels, environmental databases and output products is provided. Several studies are presented which investigate the sensitivity of the predictions to the component sub-models and/or databases used. Travel time and travel time variance predictions are compared to measured data. Finally, two example applications of the model are described; a prediction of the coverage of the International Monitoring System, and an analysis of the causes of a gap in the predicted coverage.
