Description
Summary:Our objective was to build, test, and characterize a diver-held ferrous metal detector array with real-time processing algorithms that accurately determines the position, depth, and size of magnetic anomalies from unexploded ordnance (UXO). This was accomplished by using an array of low power, miniature, total field atomic magnetometers, with a new miniaturized electronics design using a novel digital approach. We achieved order of magnitude reductions in the size and power consumption of total field magnetometers, and demonstrated the significant benefits these enable when used in arrays with real-time processing.
