Interference Suppression Techniques Development for Future Combat Scenarios

Physical Sciences Inc.(PSI) proposes to develop a fiber optic position measurement system for multi-line towed array applications. PSI's proprietary approach for fiber optic position measurement system sources and receivers will meet the requirements ofthe solicitation each with a very compact package size, nominally 0.5 inch diameter and no longer than 5 inches. George Connolly, MTI, will assist PSI, validating PMS source requirements and then PSI will complete the design of proof of principleconfigurations for at least two different concepts. These proof of concept designs will be initially tested in the laboratory and then at NUWC's Dodge Pond demonstrating proof of principle operation and that the requirements can be met by PSI's innovativeapproach. A Phase II program plan will be developed that when performed in a Phase II program, will result in a complete demonstration of the key technologies and components of the fiber optic position measurement system necessary for prototypedevelopment. The Phase I Option would be the detailed design of the Phase II system.The proposed program will develop a fiber optic position measurement system, which is an enabling technology for all-optical towed arrays. Such arrays for both DoD andcommercial applications, e.g., seismic oil exploration, have the potential of reduced costs, increased reliability, and improved performance.
