Abstract
Current state-of-the-art electromagnetic induction (EMI) metal detector research systems have shown the potential to detect low metal content buried targets as well as discriminate the type of target as a mine or clutter. However, further research is needed to investigate metal target discrimination potential for closely spaced metal targets. A series of experiments designed to investigate the spatial and time decay responses of multiple metal targets were conducted using a spatial scanning, time-domain EMI metal detector. Time decay signatures were taken of two calibration targets placed over varying distances with the objective of analyzing target identification and spatial resolution. This paper presents results of these experiments.
