| Popis: | The electromagnetic response of metallic targets is known to vary as a function of frequency. In this paper we demonstrate the ability to measure these frequency-dependent variations for buried metallic targets from stand-off sensor measurements, with a focus on its potential application to humanitarian demining. A planar measurement system is presented which is capable of measuring the trans-impedance between a transmit-receive coil pair at five simultaneous frequencies. These measurements have been calibrated against a known ferrite target to yield absolute spectroscopic responses. Three targets are presented; two surrogate anti-personnel landmines and a bullet casing. These measurements are compared with previously recorded spectra using a separate measurement system, showing an agreement in the range of 15 to 25%. |
