Enhanced UXO Discrimination Using Frequency-Domain Electromagnetic Induction

Book excerpt: The Chemistry Division of the Naval Research Laboratory has developed the Multi-sensor Towed Array Detection System for use in unexploded ordnance detection and discrimination. With support from the Environmental Security Technology Certification Program, we have developed a frequency-domain electromagnetic induction sensor array to extend the discrimination capabilities of the MTADS. We have demonstrated the system at the Standardized UXO Demonstration sites at Aberdeen Proving Ground, MD and Yuma Proving Ground, AZ. At each of the sites, we surveyed the Calibration Lanes, the Blind Test Grid, and as much of the Open Field Area as possible. In this report, we describe the sensors demonstrated, show examples of the data collected, describe our analysis methodologies, and report the detection and discrimination results as scored by management of the test sites and analysts from the Institute for Defense Analyses.
