Abstract : The MTADS Discrimination Array (TEMTADS) 5x5 array was demonstrated at the former Mare Island Naval Shipyard, CA, during July 2011 as part of the ESTCP Live Site Demonstrations. The TEMTADS 5x5 array is vehicle-towed with array position and orientation determined with cm-level GPS. TEM data are collected at each target location while the vehicle and sensor array are stopped, with an on-target collection time of approximately 1.5 minutes. The 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 approximately 2,100 unknown targets at the former Mare Island Naval Shipyard, CA.
