摘 要：Unexploded ordnance (UXO) contamination at former and current Department of Defense sites is an extensive problem. Site characterization and remediation activities conducted with the current state-of-the-art technologies at these sites often yield unsatisfactory results and are extremely expensive to implement. This is due in part to the inability of current technology to distinguish between UXO and nonhazardous items. Newly emerging electromagnetic induction (EMI) sensor technologies offer the ability to robustly distinguish between these two classes of objects. Early versions of these systems have tended to be large and designed for towed operation on open fields with good sky view to provide the necessary quality of geolocation information. The objective of ESTCP projects MR-200807 and MR-200909 was to demonstrate sensor arrays that are capable of reliably retaining the performance of one of these new technologies in a form suitable for use in rugged terrain and other environments where mobility and the viability of traditional positioning technologies are limited. The systems demonstrated in both projects are based on the transient electromagnetic (TEM) induction sensor technology that was developed under ESTCP project MR-200601.
