Users Guide to BellhopDRDC_V4: Active and Passive Versions

Abstract

The acoustic prediction model called Bellhop continues to be enhanced to more closely fit the requirements of DRDC Atlantic's Environment Modeling Manager (EMM). This version 4 contains both passive and active algorithms. In this version, linear range interpolation of the SSP and curvilinear interpolation of the bathymetry are added as input choices, and an additional output of the sampled SSP is provided. The major differences between BellhopDRDC and the web version dated May 2008 lie in the input data and file formats that have been altered to satisfy the requirements of the controlling programs within the Environment Modeling Manager. This document provides a users guide to the running of the active and passive versions of the BellhopDRDC_v4 program and the boundary loss program, and describes some plotting routines available for viewing the prediction results.
