Report on a workshop on electromagnetic induction methods for UXO detection and discrimination

To decrease cost and increase reliability and efficiency of unexploded ordnance (UXO) environmental remediation, government research and development programs and industry efforts seek to establish a practice of UXO location using modern digital survey systems, sound geophysical survey procedures, and postprocessing of data for enhanced detection and discrimination. The new practice will replace most traditional “mag and flag” type UXO location surveys that typically use analog instruments, where all detected targets (anomalies) must be investigated (i.e., excavated). Several factors, both technical and nontechnical, drive and justify the change in practice: (1) digital data allow maintenance of a permanent record of the locations of targets and sensor signatures over targets; (2) digital data will typically have higher dynamic range (hence higher signal-to-noise ratios) than the analog data that rely on audio or visual output; (3) digital data allow and facilitate postprocessing to enhance signatures for ...
