The Military Munitions Response Program (MMRP) is charged with characterizing and, where necessary, remediating munitions-contaminated sites. When a site is cleared of subsurface munitions using the methods that have been common for the last two decades, it is typically mapped with a geophysical system based on either a magnetometer or electromagnetic induction (EM) sensor and the locations of all detectable signals are excavated. The vast majority of these detections do not correspond to munitions, but rather to other harmless metal objects: often more than 99% of objects excavated are not munitions.

Classification is a process used to make a decision about the likely origin of a signal. A decade of research and development initiated in the Strategic Environmental Research and Development Program (SERDP) produced new EM sensors and analysis techniques that are able to classify munitions from clutter in controlled test environments. To demonstrate this technology in a variety of real-world environments, ESTCP conducted a series of demonstrations of these classification technologies. From 2007 to 2015, the Pilot Program has conducted 26 demonstrations, summarized in Section 2...
