International Pilot Project for Technology Co-operation A multi-national technical
evaluation of performance of commercial Participants: Abstract This report gives a summary of the methodologies and results. Detectors were assessed for performance in air; in a range of soils; and in realistic demining scenarios in Cambodia and Croatia. In addition, the human factors aspect relating to the use of each detector was assessed. The in-air tests included measurement of sensitivity, drift with time,
effect of moisture on the detector head, the assessment of the possibility to set-up the
detector consistently and measurement of the sensitivity volume relative to the sensor
head. In-soil tests provide comparison of performance in four different soil types under
carefullycontrolled conditions. The measurements in Cambodia and Croatia allow comparison
of performance measured under laboratory conditions with that achieved by deminers in
field conditions. A strong correlation was observed between the values for the magnetic
susceptibility of the soil and the performance achieved by operational metal detectors.
This suggests that such measurements should be a part of Level Two Surveys of suspected
mined areas. |
