Magnetic sensor technologies are being developed at NAVSEA, Coastal Systems Station to enhance the ability of Autonomous Underwater Vehicles (AUVs) to perform detection, localization and classification (DLC) of mines for mine countermeasures in Surf Zone/Very Shallow Water (SZ/VSW) environments. This work involves the design, development, and eventual systems integration onto AUVs of passive sensors for DLC of ferrous mines and active sensors for DLC of both non-ferrous and ferrous mines. The magnetic sensors must provide useful detection ranges and robust target localization capability for mine DLC tasks while operating aboard AUVs with challenging operational conditions of small size and power budgets, large changes in vehicle orientation in turbulent SZ/VSW areas and potentially severe electromagnetic compatibility problems. Similar technical issues must be addressed when applying magnetic sensors to solve the mission-critical problems of AUV navigation and communications in SZ/VSW environments. This paper specifically presents results from field tests of passive, DC-magnetic sensors against small ferrous targets.
