Acoustic Intercept Receiver for Naval Special Warfare Undersea Vehicles

Information Systems Laboratories (ISL) and Florida Atlantic University (FAU) propose to develop and test a system that uses existing signal processing algorithms coupled with innovative construction technology developed ISL under our E-Field sensor programs and FAU under UUV programs. The Challenge is to develop a small system package with the capability to intercept active threat emissions early enough for the underwater vehicle to avoid capture or destruction. The system needs to fit in the confines of existing and future undersea vehicles and require minimum power to operate for the duration of the mission. The system must have a compatible interface with the existing vehicle systems such as command and control, communications. The system must provide sufficient bearing accuracy and signal characterization to support identification and classification of the active emission as a threat so that tactical decisions may be made. The system must detect a wide range of threat frequencies and should be capable of filtering out the acoustic emissions of its own platform in order to prevent false alarms.
