An overview of the MASTODON sonar simulator

Abstract

The Modular Acoustic Simulation Toolset of the Department of the Navy (MASTODON) is a feature-rich ray-based sonar simulator derived from the Personal Computer Shallow Water Acoustic Toolset (PC SWAT) codebase, developed at the Naval Surface Warfare Center Panama City Division over several decades. This paper discusses the design of this new simulation architecture and gives an overview of its features and models used. New simulation capabilities will be highlighted that enable drastic speed improvements from the addition of graphics processing unit (GPU) simulation code into MASTODON’s codebase.
