The advanced technology demonstration program in 1994 was initiated by the US Army Environmental Center, at Jefferson Proving Ground, Madison, Indiana, to assess the state-of- the-art technologies applicable to detection and remediation of unexploded ordnance (UXO). A multifaceted methodology was developed for evaluating the demonstrators' results in detecting and identifying UXO targets, utilizing both spatial and nonspatial information. The evaluation process involves two major steps. The first step, called target matching, is to compare the reported targets with the known, emplaced targets, in terms of target location, depth, type, class, and other ordnace-specific attributes. The purpose of the first step is to measure a demonstrator's detection and identification capability in general, while the purpose of the second step is to analyze the matching results using statistical methods.
