Improved Torpedo Defense Navy SBIR FY2010.1 Sol No.: Navy SBIR FY2010.1 Topic No.: N101-062 Topic Title: Improved Torpedo Defense Proposal No.: N101-062-0847 Firm: 3 Phoenix, Inc. 14585 Avion Pwy Suite 200 Chantilly, Virginia 20151 Contact: Russ Jeffers Phone: (703) 956-6480 Web Site: www.3phoenix.com Abstract: The proposed Phase I investigation is expected to yield innovative technologies for resolving closely spaced torpedo salvos approaching near endfire of towed array sensors. The approaches include active and passive signal processing methods that exploit physical phenomena characteristic of submerged, dynamic sound sources as well as false alarm reduction techniques afforded by multiple modalities. 3 Phoenix has extensive experience in the development of sensor processing technology and has been successful in transitioning leading edge technology to defense applications. We anticipate that the results of this effort will demonstrate the feasibility of the system approach and the path to implementation. Benefits: The Phase I effort will provide a basis for assessing the feasibility of the proposed technologies. The performance analysis from Phase I is considered theoretical because it is not based upon a fully implemented system, but the use of sea test data will allow for an accurate assessment of endfire torpedo salvo detection performance that will be documented in a technical report. This analysis will establish which components of the proposed technologies are successful and provide a basis for establishing performance metrics, and for estimating the computer/processing requirements, maintenance, and cost of a complete system. The algorithm implementations from Phase I will be used as a testbed during Phase II to investigate the performance at the system level. Key parameters will be tested in a lab, or during a sea test if possible. Return
