Summary
 Airborne magnetic systems for mapping unexploded ordnance (UXO) and other shallow metals have been developed at Oak Ridge National Laboratory (ORNL) over the past five years .We have recently completed testing of a time-domain electromagnetic (EM) system to supplement the magnetic system for UXO investigations. The test
was conducted at the Badlands Bombing Range (BBR) in South Dakota in September 2002. In this paper, we present a comparison of the magnetic and EM data from a bombing target within the BBR and suggest an approach for further integration of the two data sets, as well as opportunities for deploying this system for other types of surveys.
