The Man-Portable Vector MPV sensor was demonstrated at a live site at the Former Waikoloa Maneuver Area on Hawaii in January 2014 as part of the ESTCP Live-Site Program for Munitions Response. The MPV is an electromagnetic induction EMI sensor designed for munitions detection and classification. Its handheld form factor provides enhanced portability and ruggedness relative to vehicular-based systems. The Waikoloa site brought new challenges with the occurrence of multiple rocky outcrops that precluded use of vehicular-based systems, and soils with high magnetic remnant magnetization that caused sufficient geologic background noise to hide the response of buried objects. The study focused on a 1.5-acre parcel where targets of interest included 37 mm projectiles, 60 mm and 81 mm mortars. The MPV was first utilized for a detection survey after which 450 anomalies were selected for cued interrogation in standard cued mode. The detection survey was generally successful at covering the entire site and detecting potential targets. Classification of the cued data resulted in all UXO being correctly identified with 81 clutter rejection.
