SBIR-STTR Award

This project is to develop acoustic processing algorithms and implementation methods using sparker acoustic sources for rapid real-time environmental measurements Phase I will evaluate innovative approaches using modeling simulations and sparker experimental data for validation. The proposed approach will employ direct transmission measurements, developing algorithms that take advantage of the repeatability of sparker, the capability to emit multiple pulses, as well as the possible use of real time measurements at the source. In Phase II the new modeling and implementation approach design will be implemented and tested at sea for SEA. The long-term goal is to develop innovative acoustic processing algorithms and implementation methods to support the successful transition of a sparker based SEA buoy to the fleet for rapid real-time environmental measurements.

This Phase II is to establish approaches for using sparker acoustic sources to meet requirements for the SEA program. Phase II will continue testing, analysis and modeling, similar to Phase I, to establish environmental measurement capabilities with the sparker and develop source level specifications. Phase II also includes further development of two types of sparkers (annular and wire-initiated), to optimize them for output in the acoustic frequency bands of interest for SEA, and to select the best scenario for SEA. The end result of Phase II will be a transition plan for SEA to be implemented in Phase III.
