Paper Abstract

The use of Electromagnetic Induction (EMI) for land mine detection has been common for over six decades. Recent work in this field has focused on greater discrimination due to the difficulties in detecting mines amongst metal debris. The false alarm rate of such systems could be improved by the ability to discriminate between metal types. This paper presents initial results of a study into metal discrimination using a multi-frequency metal detector. Factors affecting the performance of such a system, including the choice of frequencies, and the mine size, orientation and metal composition are discussed. This work was carried out as part a UK MoD funded Program.
