This demonstration report describes the data collection, processing and analysis of cued-interrogation data collected with Sky Researchs 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 reliabilityrobustness, 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 cant 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 reliabilityrobustness was only partially met due to the electrical issues with the orientation sensor on the Novatel SPAN.
