Demonstration of Airborne Electromagnetic Systems for Detection and Characterization of Unexploded Ordnance at the Badlands Bombing Range, South Dakota. Revision 3

摘要

This report describes a set of field tests conducted at Badlands Bombing Range (BBR) in South Dakota in September 2002. The primary goal of the field tests was to evaluate parameters critical to the design of an airborne electromagnetic system capable of detecting a variety of buried ordnance. The resulting system, called ORAGS-TEM, was patterned after the low-flying helicopter magnetic systems under development at ORNL through separate SERDP/ESTCP programs. Thus, the ORAGS-TEM has a frame mounted, multiple sensor design that permits helicopter surveys at altitudes as low as one meter over UXO-contaminated terrain. As with the magnetic systems, GPS and laser altimetry provide precise positioning to within a few tens of centimeters.
