Topological Matched Filtering for Active Sonar

Not Available Under Office of Naval Research (ONR) sponsorship entitled Investigations of Internal Waves Around Steep Slopes and Their Influence on Convergence Zone Formation, Oceanit measured internal waves two miles offshore of Sand Island in Mamala Bay, Oahu using a thermistor string and an acoustic doppler current profiler (ADCP). Internal Wave Surface Expression Sensing will develop a system of integrated sensors in an attempt to demonstrate the relationship between internal wave activities measured in the water (as developed and demonstrated with ONR sponsorship) with surface expressions observed using x-band radar and optical sensors. The resulting technology can be incorporated into littoral zone surveillance networks as well as City & County of Honolulu's sewage treatment plant operations.
