Abstract
Many technologies are being developed to improve the detection of buried threats (e.g., landmines) and to discriminate these threats from clutter in an operational environment. Current systems have implemented ground-penetrating radar (GPR) and electromagnetic induction (EMI) sensors. The detection performance of these systems is assessed in field testing, where algorithms are used to determine when a buried threat has been encountered [1]. Similar to work done by Rosen and Ayers [2], this paper focuses on developing a method to study EMI sensor performance independent of any aided target recognition (ATR) algorithm used. Rosen and Ayers developed a method and a simple metric for assessing the mine-detection capabilities of down-looking GPR systems before an ATR algorithm is applied. This paper reports the development of two metrics for a wide-band EMI sensor based on the method used by Rosen and Ayers. In this initial effort, the values of the metrics developed are presented over different targets, and observations are made regarding potential use of this metric.
