Undersea Sensor Network Performance Modeling and Cost Tool

The US Navy has a need for a tool capable of estimating the performance and cost of a cabled fixed distribution system. This model must be able to provide incremental cost changes to real-time interactive changes applied to the system (moving cables, adding sensors etc). Applied Ocean Sciences proposes a high-fidelity sonar performance prediction model built with state-of-the-art recent parabolic equation (PE) modeling, coupled with dynamic ambient noise predictions from satellite AIS and surface wind measurements. The performance tool will compute the specific sensor performance in the noise field and compute the cumulative probability of detection for a target transiting a barrier, or patrolling within a field of sensors. The cost model will be based upon publicly available (and industry survey) sensor costs including hydrophones, vector sensors, arrays, cables, power supplied, undersea network boxes etc. Both codes will be integrated within an interactive immersive 3D environment for visualization. Unclassified models will have simple costing, but detailed costing will be developed in Phase II in a classified environment.
