EMI Array for Cued UXO Discrimination ESTCP MM-0601 Demonstration Data Report. APG Standardized UXO Test Site

摘要

A new time-domain EMI sensor for the purpose of UXO classification under ESTCP project MM-0601 has been constructed and characterized. A vehicle- towed, 2m x 2m array of 25 of these sensors was demonstrated at the Aberdeen Test Center. The array was used as part of a two-step process for identifying and classifying buried metal targets where the anomalies for cued investigation were previously identified with a survey system. The resultant data (625 bi- static pairs) therefore have near-perfect spatial correlation and no motion- induced noise. The performance of the system is evaluated in terms of the performance metrics established in the demonstration plan, in part using the recently published ATC scoring report.
