Abstract: In this SBIR project Wagner Associates will develop Passive sonobuoy Association, Classification, and localization (PAC) algorithms to maximize the effectiveness of current and emerging passive sonobuoy patterns and to minimize operator task load when monitoring these fields. In particular, we will develop innovative and sophisticated contact association algorithms to associate passive sonobuoy lines-of-bearing (LOBs) that are not obtained simultaneously; since this will be the dominant case when operating against diesel submarines with very short detection ranges, especially in irregular and highly variable littoral environments. In this project we will leverage our extensive prior work developing and evaluating U.S. Navy ASW data fusion systems.
Benefits: Expected benefits of such automated and accurate contact association and target classification algorithms include reduced time to detect and classify a submarine target of interest, reduced operator task load, and significantly improved situational awareness and threat assessment. In Phase II we will develop full-scale Association, Classification, and localization (PAC) algorithms that will allow us to demonstrate how powerful passive sonobuoy data fusion techniques designed to maximize military effectiveness, can significantly improve the effectiveness of United States ASW assets. Improved ASW mission effectiveness technologies such as these are particularly necessary at a time when the United States is facing a sophisticated threat in difficult littoral environments, such as China, Korea, and the Middle East, with reduced resources. More effective detection of threat submarines will produce more effective operations, conducted at lower risk, resulting in fewer casualties to friendly forces and improved overall United States Navy and Joint Forces effectiveness.
