Acoustic Counter Detection Tactical Decision Aid Navy STTR FY2014.A Sol No.: Navy STTR FY2014.A Topic No.: N14A-T016 Topic Title: Acoustic Counter Detection Tactical Decision Aid Proposal No.: N14A-016-0029 Firm: Ocean Acoustical Services and Instrumentation Syst 5 Militia Drive Lexington, Massachusetts 02421 Contact: Kevin Heaney Phone: (703) 346-3676 Web Site: www.oasislex.com Abstract: In this STTR, OASIS Inc, with partners the Massachusetts Institute of Technology (MIT) and the Applied Physics Laboratory - University of Washington (APL-UW) proposes to develop an innovative, interactive submarine acoustic counter detect TDA for use by the Submarine Mission Planners, within the AN/BYG-1. Communicating the environmental and tactical uncertainty is of primary importance when presenting vulnerability to the fleet users either in the planning of future evolutions, or in real-time situational awareness. To this end, a system-wide approach inclusive of uncertainty will be applied. Oceanographic uncertainty will be handled via ensemble forecast system of MSEAS, the MIT real-time forecasting of oceanographic properties with uncertainty. This oceanographic uncertainty, as well as geo-acoustic (via LFBL) and positional uncertainties will be included in the computation of the acoustic field (TL). Ambient noise variability and the projection of beam noise to a threat geo-located somewhere distant from the measurement platform will be addressed. During Phase I, a prototype graphical user interface, utilizing geo-referenced 2D plots will be designed. Benefits: The integration of environmental uncertainty, acoustic propagation modeling and an intuitive user interface has a significant opportunity for transition to the oil and gas exploration community. There is currently a significant push within the European Union and the Bureau of Ocean Energy Management (BOEM) to have a common acoustic take level estimate using the best available science. This framework must include environmental variability and high fidelity, efficient acoustic computations. A web-based take-estimate computational engine, accessible from the oil industry, the government and the environmental lobby would be a significant step forward. Return
