f EVALUATION OF DETECTION SURVEY ANOMALY AMPLITUDES AND ADVANCED CLASSIFICATION RESULTS OF UNEXPLODED ORDNANCE GEOPHYSICAL SURVEYS

Recent studies show the ability of next generation time domain electromagnetic (TDEM) instruments, such as Geometrics’ MetalMapper, to discriminate unexploded ordnance (UXO) from nonhazardous clutter. However, the success of next generation instruments and their requisite advanced classification techniques rely on initial detection surveys using state of practice instruments. These detection instruments, such as Geonics’ EM61-MK2, have certain detection limits as a function of UXO size and depth. It is less certain how advanced classification techniques successfully discriminate anomalies at the lower limit of detection.
