An inverse scattering approach is presented to detect, localise and estimate the geometry of buried dielectric targets, in a 2D scenario, by exploiting magnetic sources as transmitting antennas. Explicit formulas to compute the scattered field from dielectric anomalies are derived for both homogeneous and half-space background scene. A linear inverse scattering approach is formulated and analysed for both the scenarios; finally, the performance of the two proposed approaches is tested against full-wave finite-differences in time-domain (FDTD) data simulating the exact scattering phenomenon.
