Low-Cost Biodegradable Massive Sensor Networks for Submarine Detection

The proposed SBIR Phase II program would implement a multi-sensor system for the detection of submarines at close range in littoral waters. During Phase I, NanoSonic examined several options and downselected these options to a single implementation. In cooperation with a major DoD contractor intimately involved in distributed littoral battlespace sensor systems, NanoSonic will build a prototype system for evaluation and use in a simulation model for the larger array. The system will implement a magnetic detection scheme in which a widely distributed sensor array will form a barrier with bounded probability of detection and false alarm rates. NanoSonic will also continue to characterize and adapt a unique magnetic sensor for specific application to this program. The sensitivity of this sensor exceeds that of other low-cost magnetic sensors. NanoSonic would continue to work with Virginia Tech researchers who have specific experience with small autonomous underwater platforms and their cooperative navigation, search and track functions. This system will indicate and localize submarine contacts while complementing existing acoustic systems. NanoSonic specifically anticipates the transition of developed technology in cooperation with the DoD contractor. The NanoSonic PI has direct experience in the defense industry with sensors, propagation and systems engineering.
