High Frequency Omni-Directional Acoustic Sensor with Open Architecture Telemetry

The DON26BZ02-NV046 project seeks to develop a high-frequency, omnidirectional acoustic sensor with accurate bearing determination for integration into Open Architecture Telemetry (OAT) towed arrays. This technology aims to improve the detection and localization of undersea entities, addressing the current lack of commercially available solutions that combine high-frequency, omnidirectional detection with bearing capabilities. The sensor must be robust for towed array deployment, able to withstand harsh environmental conditions, speeds up to 30 knots, and depths to one mile, with a diameter smaller than 2 inches to minimize flow disruption. The project is restricted under ITAR/EAR, requiring U.S.-owned contractors with security clearances, as Phase II work may become classified. Phase I involves concept development and feasibility analysis, while Phase II focuses on prototype development and testing in controlled water environments. Phase III will support the Navy's transition of the technology for military use, with potential dual applications in oil and gas exploration and environmental sensing.
