2010 ESTCP UXO Classification Study Rougemont, NC, ESTCP MR-1034, Demonstration Data Report, Former Camp Butner, MTADS Discrimination Array (TEMTADS) Survey
Abstract
A twenty-five element planar array of transient electromagnetic induction (TEM) sensors developed by the Naval Research Laboratory under SERDP and ESTCP sponsorship was deployed to the former Camp Butner, NC as part of the ESTCP UXO Classification Study in July 2010. The TEMTADS array is used in a cued interrogation mode. It is delivered by a tow vehicle to a series of GPS-flagged locations corresponding to anomalies detected during prior digital geophysical mapping of the site. Data are collected at each target location while the array is stopped. Several hundred anomalies per day can be interrogated in this fashion at sites like the former Camp Butner. The array data are inverted to determine the principal axis eddy current decay functions of the targets. Classification is based on comparing the eddy current decay functions for each target with those of the various munitions targets of interest at the site, as well as a variety of clutter items that are representative of the non-hazardous metal debris at the site. We report the classification performance results with the TEM array for roughly 2,000 unknown targets at the former Camp Butner.
