Abstract:

Explosive ordnance disposal EOD technicians require the capability for standoff detection and classification of buried anomalies. Current fielded man-portable sensors provide little to no standoff detection and no classification of detected anomalies. The development and demonstration of techniques for standoff detection and classification of buried metallic and non-metallic unexploded ordnance UXO will result in a prototype man-portable multi-element electromagnetic sensor array system. The objectives of this program are to 1 Collect experimental time domain electromagnetic TDEM data to determine baseline EM signatures of targets with simple geometrical shapes, 2 Use the experimental data to validate results and theoretical knowledge to develop computer algorithms for forward and inverse modeling of the responses of TDEM systems to UXO targets these algorithms will be the basis for characterization of buried anomalies, and 3 Assess the capability of a multi-element magnetic field sensor array to detect buried UXO-like items and classify detected items as UXO or non-UXO shaped. More specifically, demonstrate that a giant magnetoresistive GMR or high temperature superconducting quantum interference device HT SQUID multi-element gradient sensor can determine the location of a UXO item at an appropriate range relative to target size and magnetic signature e.g., a 150 mm projectile at a range of 4 meters with an EM source and provide information for shape assessment.
