Abstract
A broadband electromagnetic induction (EMI) sensor array is developed to help discriminate between types of metallic targets. The sensor uses a single dipole transmit coil and an array of four quadrapole receive coils. The sensor operates in the frequency domain and collects data at 15 logarithmically spaced frequencies from 1 kHz to 90 kHz. The system is designed to be very sensitive while making very accurate measurements. The accuracy is very important to be able to filter out soil effects and to effectively classify targets. Experimental results are presented to show the accuracy of the system.
