A phase I study is proposed to verify the technical feasibility and Refine the concept design for a submarine-installed ice thickness And profiling measurement system. The system in real-time will provide a continuously updated 3-d display of the under-ice surface plus Accurate measurement of ice thickness. The system provides immediate And necessary information for rough-ice deployment and for high speed maneuvers under the pack ice. The design concept in a more Simplified form, has direct application to seabed deployed ice Measurement equipment. The proposed system utilizes a variable low Frequency parametric sonar approach to determine the overhead ice Thickness. The system also depicts a real-time 3-d projection of the Under-ice surface. The estimated profiling range and ice thickness capability are 1,000 meters to 10 meters, respectively. Successful completion of phase I would lead into a breadboad demonstration and preliminary design prerequisite to operational deployment.
