Automated Passive Target Signature Fusion

Despite significant advances in acoustic processing and data display techniques, passive sonar classification still involves a significant amount of human effort. During Phase I, Sonalysts, Inc. developed a proof-of-feasibility approach to an automated passive target signature fusion rule base, focused on the similar source fusion (SSF) requirements of the DDG-1000 program. Relying on our unequaled expertise in passive and active sonar classification, as well as surface and air undersea warfare (USW) operations, modeling, and simulation, our innovative technical approach focused on the development of a set of deterministic and heuristic rules that represents the passive sonar classification process. Sonalysts’ Phase II efforts will expand on this technological success by implementing all the applicable SSF rules in a Prototype Automated SSF (AutoSSF) Module, and integrate that module within a realistic simulation of a USW tactical environment. The purpose of this integration will be to support dynamic testing and demonstration of our innovative technical approach, as well as to experiment with notional and prototypical operator user interfaces for viewing the data output of the AutoSSF module.
