While discrimination methods for distinguishing between real mines and metal fragments would greatly increase the efficiency of demining operations, no practical solution has been implemented yet. A potentially efficient method for the discrimination of metallic targets using metal detectors uses a high-precision robotic manipulator to scan the minefield. Further field research is needed, however, before this method can deploy for operational use.
