One of the key limits to the detection range and bearing resolution of towed array sonar systems is the fact that the towed array cable will bend due to ocean currents and towing vessel maneuvers. There is therefore a need within the Navy for sensors that are able to measure and accurately quantify the cable attitude at regular intervals along the cable length. The sensor has to be accurate enough to meet Navy requirements and small enough to fit inside the towing cable. We propose to complete the development of a novel heading sensor that can be seamlessly integrated with the towing cable. Our innovative sensor will provide highly accurate measurements of magnetic heading and roll angle of the cable. Our sensor is based on novel miniature magnetic sensor technology and will be packaged to withstand the high pressure and low temperatures of typical underwater missions. Our heading sensor will be inexpensive, small, highly reliable, and consume only a small amount of power. Results of our Phase I project clearly demonstrate the feasibility of our innovative heading sensor concept and provide strong justification for Phase II continuation.
