CHARLES RIVER ANALYTICS, INC. — Department of Defense SBIR Phase I: Tactical electromagnetic environments have become much more complex over the last two deca

Description

Tactical electromagnetic environments have become much more complex over the last two decades with a higher density of more diverse and more sophisticated emitters. Signals of interest are becoming much more frequency agile and have a lower probability of intercept, making it much harder to detect and identify them. To support the Navy in maintaining a combat advantage in dense signal environments, we propose a System for Efficient Agile Signal Classification of Adversary Produced Emitters, or SEASCAPE. SEASCAPE provides an energy-efficient, dynamic, hierarchical ensemble classifier that accurately fingerprints sophisticated emitters while characterizing detection uncertainty and reliability. SEASCAPE is supported by a signal processing workbench and a fusion module to evolve the classifier and its supporting feature sets over time as new agile signals of interest are encountered.
