Abstract
In August 2005, numerous test events were conducted in Narragansett Bay (under adverse, moderate, and high signal-tonoise ratio (SNR) conditions) to validate shallow-water acoustic-based detection, localization, and ranging algorithms against surface craft and divers. These measurements were completed at the Naval Undersea Warfare Center Division Newport's Broadband Ocean Acoustic Laboratory, which is a shallow-water development facility for evolving acoustic and light-based technologies that are of interest to the U.S. Navy in areas such as Force Defense and Port and Harbor Security. It is shown that relatively common ambient environmental conditions in Narragansett Bay (such as wind speeds greater than 15 knots) create adverse acoustic conditions and generally poor target detection performance. As expected, the acoustic-based algorithms performed well at moderate to high values of SNR.
