The response function of a specific case of object shape - a homogenous sphere from ferromagnetic and non-ferromagnetic material is introduced. Experimental data measured by a metal detector excited with a linearly frequency-swept signal are presented. As a testing target various spheres from different materials and sizes were used. These results should lead to better identification of the buried object.}, type={Artykuły / Articles}, title={Metal Detector Excited By Frequency-Swept Signal}, URL={http://www.czasopisma.pan.pl/Content/89742/PDF/Journal10178-VolumeXVIII%20Issue1_06%20paper.pdf.pdf}, doi={10.2478/v10178-011-0006-3}, keywords={Metal detection, Polyharmonic signals, Frequency Sweep, Modelling of electromagnetic induction, Analog signal processing}, }
