ABSTRACT:The primary technical objective of this demonstration project was to evaluate the detection and discrimination capabilities (including production rates and costs) of advanced UXO systems in difficult magnetic clutter environments such as those encountered at Kaho'olawe, Hawaii. One 90-m by 111.1-m (1-hectare) area and 10 (not necessarily contiguous) 30-m by 30-m test grids within the Kaho'olawe Quality Assurance (QA) Range were prepared to present a limited range of target/clutter/ topography/vegetation/magnetic background conditions to the various demonstrators' systems: Geonics EM-63, GTL TM-5 EMU, Geophex GEM-3, NRL EMMS, and Geonics EM-61. Anomaly maps, survey maps, and demonstrators target discrimination charts are compared to actual groundtruth to determine performance assessment of detection, discrimination, and false alarm rate. At Kaho'olawe, the advanced EMI systems did not demonstrate significant performance and/or cost improvements over the baseline technology consisting of a standard EM-61 system operated in an "EM and Flag" mode. This was not true at Jefferson Proving Ground, Indiana (July 2000). Finally, the safety and logistics problems associated with conducting technology demonstrations concurrent with actual UXO cleanup operations proved to be a very inefficient, costly, and time-consuming process.
