Abstract : This demonstration report describes the data collection, processing and analysis of cued-interrogation data collected with Sky Research's SKY3D vehicular platform at the Pole Mountain Target and Maneuver Area (PMTMA), near Laramie, WY. SKY3D integrates a MetalMapper sensor, real-time-kinematic global positioning system and inertial measurement unit (in the form of the Novatel SPAN) and a custom user interface on a Kubota all-terrain-vehicle. Cued interrogation data were collected by dwelling for 30 seconds over 2,370 anomalies previously identified via a full-coverage geophysical survey of part of the Bisbee Area of PMTMA. The data collection was conducted in the field over a 14 day period in July and August 2011. Production rate was as high as 39 points per survey hour with a maximum of 326 anomalies visited in a day. In this demonstration report we evaluate eight identified performance metrics for the technology including four pertaining to the data collection (reliability/robustness, survey rate, percentage of site covered, MetalMapper sensor position accuracy) and four to the subsequent processing and classification of the collected data (percentage of munitions correctly identified, reduction in false-alarm rate, appropriate specification of stop-dig point and minimization of can't analyze anomalies). Six of the eight performance objectives were easily achieved, while one objective, 90% of MetalMapper positions within 30 cm of each Target of Interest (TOI), was missed by 1 cm (90th percentile at 31 cm). The last and only qualitative objective on reliability/robustness was only partially met due to the electrical issues with the orientation sensor on the Novatel SPAN.
