The Chemistry Division of the Naval Research Laboratory has developed the Multi-sensor Towed Array Detection System MTADS for the detection and classification of buried unexploded ordnance. In order to increase the discrimination ability of the system, we have developed advanced analysis algorithms for the Electromagnetic Induction EMI sensor data. In order to critically test the performance of these algorithms, we performed a magnetometer and two EMI surveys of a seeded, 10-acre site on the Impact Area of the Badlands Bombing Range, SD. We quantitatively compare the predictions from a baseline MTADS magnetometry analysis, an advanced EMI analysis, and a probabilistic neural net approach developed in a related SERDP program against actual remediation results. In addition, we discuss the performance the EMI system in both a low- and high-SNR environment.
