Low Cost Sonobuoy Technology Applied to Towed Arrays

The objective of this program is to develop a low cost hydrophone for use in towed line arrays. To this objective, Phase I will identify and develop hydrophone array assemblies using cost-effective hydrophone designs. This will be accomplished through the use of sonobuoy technology as related to design and manufacturability. During Phase I the specification requirements for the array will be determined and a new hydrophone element design will be developed. The hydrophone elements will be designed into an subarray. This subarray will be of a form factor that direct replacement of current subarrays may be accomplished. This program will identify the hydrophone design, the methodology of manufacturing for the hydrophone element and the subarray, and an assessment of the required manufacturing labor. In addition, the cost of the proposed subarray design will be determined as purchased in quantities of 4000. Phase I will also demonstrate, that the proposed hydrophone element meets the design specification. It will also show how the hydrophone element is integrated into the subarray. It will show how the hydrophone could be developed into a family of hydrophones that apply to a wide range of subarrays for towed array applications.
