Abstract : A project investigating detection and discrimination techniques for total field magnetometers and multiaxis gradiometers is being performed under the Unexploded Ordnance (UXO) Clearance Technology Program sponsored by the U.S. Army Environmental Center and managed by the Naval Explosive Ordnance Disposal Technology Division. The project was developed to address the Government's need for reliable, efficient, and cost effective UXO clearance technology. This need has become a priority within the Department of Defense because of military downsizing, reductions, and base consolidations, and the need to close, clean up, and return military bases and ranges to the public. Arete Engineering Technologies Corporation developed an automatic processor for use on the Subsurface Ordnance Characterization System which has an array of cesium vapor magnetometers. The processor is a stand alone computer code, written in Ansi C, which automatically (without an operator) detects and characterizes magnetic anomalies. The prototype processor performs five major subtasks: (I) data input and mapping, (2) noise preprocessing, (3)threshold detection, (4) parameter estimating, and (5) target output information. It serves as a baseline algorithm for future software efforts. This report discusses the major program algorithms, their theoretical bases, and overall program logic flow. In addition, processor upgrade paths are identified for near and long term efforts.
