Abstract

A broadband electromagnetic induction (EMI) sensor is developed to help discriminate between buried land mines and metal clutter. The detector uses simple dipole transmit and receive coils along with a secondary bucking transformer to mostly cancel the coupling between the coils. The technique allows the cancellation that can be obtained using a quadrupole receive coil while maintaining the depth sensitivity and simple detection zone of a dipole coil. Experimental results are presented for several targets.
