Quality Control Methodologies for Advanced EMI Sensor Data Acquisition and Anomaly Classification - Former Southwestern Proving Ground, Arkansas

Abstract : This report details a live site demonstration project conducted by WESTON at the former Southwestern Proving Ground (SWPG) as part of Environmental Security Technology Certification Program (ESTCP) Munitions Response Project MR-201231. The purpose of the project was to demonstrate the effectiveness of the advanced sensor and classification methodology for identifying targets of interest (TOIs) at a site containing a diversity of munitions in high concentrations. A total of 11.23 acres of dynamic surveys were conducted using MetalMapper advanced electromagnetic induction (EMI) sensor. A total of 2,116 targets were selected from the dynamic data for cued investigation, and 1,398 targets were intrusively investigated. The classification methodology resulted in the correct classification of 100% of TOI and yielded a reduction in clutter digs of 83%.
