Detection of land mines

The General Theory of Metal detection is given in the earlier portion of the paper. The conflicting influences of conductivity and ferromagnetism are stressed and the difficulty of detecting metallic mines in magnetic soils is explained. The latter half of the paper deals with the principles of operation, description and comparative performances of a few mine detectors now in service use. Towards the end mention is made about the possibilities of tackling the problem of non-metallic mine detection..
