GelMan Thoracic Surrogate for Underwater Threat Neutralization

Abstract

Hostile underwater swimmers are a potential threat against military and commercial shipping anchored in civilian, military or dual-use ports and harbors. Conventional defensive methods to quickly disable or defeat such a threat may pose a risk of injury or death to non-hostile individuals on vessels engaging in routine activities in the same area. An alternative concept is to add an Underwater Threat Neutralization (UTN) system, based on directed low frequency underwater ensonification for swimmer detection and tracking. The goal of this work is to develop an instrumented human surrogate technology to demonstrate how acoustic energy at specific frequencies, sound pressure levels and time durations would be predicted to affect hostile swimmers at various depths and orientations, since the demonstration and validation of such a system on human test subjects is not ethically possible.
