Evaluation of Discrimination Technologies and Classification Results Live Site Demonstration: Former Waikoloa Maneuver Area

Abstract : The project involved the processing and analysis of dynamic EM61-MKII data and a cued survey of 1,032 dynamic EM61 data targets with the MetalMapper at the former Waikoloa Maneuver Area. The Cued MetalMapper data were analyzed and the dig list submitted was scored against the ground truth from the intrusive investigation and the blind seeds present in the survey area. Nine seed items placed within the demonstration areas were incorrectly classified as either clutter or soil response on BTG s final dig list. It was concluded that the effects of the background response due to site geology were too significant to allow the correct classification of these targets regardless of processing method. Therefore, the project failed the performance objective of correctly identifying all TOI at the site. Because it was concluded that all targets at the site needed to be excavated to ensure the recovery of all of the TOI, the project failed the performance objective of reducing clutter digs by more than 75%. It was recommended that all anomalies identified in the EM61 detection survey be investigated to ensure that all TOI were recovered.
