Reducing Tensor Magnetic Gradiometer Data for Unexploded Ordnance Detection

By Robert E. Bracken and Philip J. Brown

This research was supported by the U.S. Department of Defense through the Strategic Environmental Research and Development Program (SERDP)

We performed a survey to demonstrate the effectiveness of a prototype tensor magnetic gradiometer system (TMGS) for detection of buried unexploded ordnance (UXO). In order to achieve a useful result, we designed a data-reduction procedure that resulted in a realistic magnetic gradient tensor and devised a simple way of viewing complicated tensor data, not only to assess the validity of the final resulting tensor, but also to preview the data at interim stages of processing.
