Abstract
The U.S. Navy has researched the use of various acoustic sensing technologies that exploit the deep water reliable acoustic path (RAP) using vertical line arrays (VLA’s) of vector sensors with success. The buoys used were, however, large, over-the–side deployed, research systems to demonstrate the approach. What is desired is a viable approach that is smaller and can be ideally packaged to facilitate ease of handling for Naval crewmen. Phase I will perform analytical modeling studies of the required system and subsystem components to determine the suitability for RAP VLA operation and do some sensor proof-of-concept evaluations to supplement the modeling. The objective is to establish a cost effective, easily deployable, RAP sensor system that can be prototyped and demonstrated in Phase II. Component level technologies to be evaluated include miniature low noise vector sensors, array electronics and telemetry, DC power generation and distribution, and acoustic communications between the array and a surface platform. System level technologies include end-to-end array design, conventional and advanced signal processing techniques suitable for a deep water vector sensor line array, packaging and deployment concepts, and communication modalities.
