PLEASE DO NOT RETURN YOUR FORM TO THE ABOVE ORGANIZATION. 1. REPORT DATE (DD-MM-YYYY)2 Approved for public release; distribution is unlimitedThe Man-Portable Vector electromagnetic induction sensor is a new-generation instrument designed to extend classification of unexploded ordnance (UXO) to sites where vegetation or terrain limit access to vehicle-based advanced geophysical platforms. The MPV participated in the ESTCP live-site demonstration at former Camp Beale, California in June 2011, where data were collected in cued interrogation mode over 911 anomalies at a site with variable forest density and sloped terrain. Data were distributed to ESTCP partners for analysis and processed as part of this study. Demonstration objectives were attained. All buried targets of interest were detected and recommended for excavation through geophysical inversion and statistical classification. The prioritized dig list achieved over 80% reduction in unnecessary clutter excavation. Sensor positioning solely relied on the MPV-dedicated, prototype beacon positioning system. The method proved to be reliable and accurate within classification requirements (1-2 cm accuracy). The MPV technology will be involved in further ESTCP demonstrations in 2012.
