While a lot of improvement has been achieved with metal detectors in detection depth and ground rejection, little effort has been directed toward better discrimination capabilities; high false-positive rates not only increase clearance time, they tend to lower deminer vigilance, causing accidents. The authors have modeled a statically operating, off-the-shelf metal detector by generating volumetric sensitivity profiles. They present in-laboratory measurements and results of experiments on a test demining site in Cambodia. This article aims at giving deminers a more informed view of metallic targets, allowing them to take differentiated actions during target identification and removal.
