Target response coefficients for three pipe nipples intended as surrogates for commonly encountered UXO items were calculated from measurements made using the recently developed NRL Time-domain Electromagnetic Induction array. These response coefficients were used to predict the signals expected from an EM61-MK2, the most commonly used geophysical survey instrument for UXO, for each of the three items as a function of orientation and distance of the center of the item ...
Target response coefficients for 13 commonly encountered UXO items were calculated from measurements made using the recently developed NRL Time-domain Electromagnetic Induction array. These response coefficients were used to predict the signals expected from an EM61-MK2, the most commonly used geophysical survey instrument for UXO, for each of these items as a function of orientation and distance of the center of the item below the bottom coil of the sensor. ...
