Development, testing and demonstration to towed acoustic arrays from underwater gliders in pursuit of navigable, persistent assets.
Abstract
Over the past twenty years, autonomous underwater vehicles have demonstrated the ability to collect high-fidelity acoustic measureme nts, produce summary datasets that can characterize background noise, and provide detection and tracking of adversarial sub-sea targ ets in the area of operation. Prior UxV acoustic sensing networks lacked scalability and persistence, driven by maximization of acou stic performance instead of optimizing sensing technology with respect to the UxV host systems and acoustic sources of interest. The se systems were developed based on high-cost boutique host vehicles, instead of lower-cost, reproducible systems with demonstrated p erformance in expeditionary applications. We propose the integration of platform-optimized towed array acoustic sensing solutions wi th autonomous underwater gliders proven in expeditionary operation, for persistent environmentally-aware acoustic sampling in ASW-th emed measurement campaigns. These systems will be cooperatively operated asa network so as to provide spatial coverage without empha sizing active navigation, instead distributing assets across a domain of interest or geographic choke point.
