Abstract

The aim of this paper is to present preliminary experimental results on the performance of RTD Fluxgate magnetometers in security applications. The presence of a metallic object near the sensor can be detected by measuring the weak perturbation of geomagnetic field distribution produced by the magnetic permeability of the material from which the object is made. Results are presented by the use of ROC curves, a widely used formalism to evaluate the performance of binary classifiers.
