Novel Sensor Geolocation Technology for Detection and Discrimination of Unexploded Ordnance1

ABSTRACT Reliable and accurate geolocation is essential for robust detection, discrimination and remediation of unexploded ordnance (UXO) and other munitions and explosives-of-concern (MEC). The MEC characterization and ,remediation activities using the currently available detection and geolocation technologies often yield unsatisfactory results, and are extremely expensive, due mainly to the inability of the current technology to detect all MEC present at a site, and their failure to discriminate between MEC and non-hazardous items. This is a consequence,of insufficiently accurate relative geolocation information of the electromagnetic (EM) sensors, since multiple EM images are combined together to produce 3D images of the buried objects, which are often blurred due to the poor sensor geolocation. As a result, most of the cost (90%) of MEC remediation
