Wide-band Electromagnetic Induction Sensors (WEMI) have been used for a number of years insubsurface detection of explosive hazards. While WEMI sensors have proven effective at localizingobjects exhibiting large magnetic responses, detecting objects lacking or containing very lowamounts of conductive materials can be challenging. In this paper, we compare a number of targetdetection algorithms in the literature in terms of detection performance. In the comparison,methods are tested on two real-world data sets: one containing relatively low amounts of groundnoise pollution, and the other demonstrating highly-magnetic soil interference. Results are quantitativelyevaluated through receiver-operator characteristic (ROC) curves and are used to highlightthe strengths and weaknesses of the compared approaches in hand-held explosive hazard detection.
