A broadband electromagnetic induction (EMI) sensor is developed to help discriminate between buried landmines and metal clutter. The detector uses a single dipole transmit coil and an array of three quadrapole receive coils. The sensor operates in the frequency domain and collects data at 21 logarithmically spaced frequencies from 300 Hz to 90 kHz. Experimental results are presented for several targets.
