Imaging of 3D magnetic targets from multiview multistatic GPR data

Ground Penetrating Radar surveys aimed at imaging magnetic anomalies are gaining an increasing attention in several applications. In this respect, we introduce in this communication an inverse scattering strategy based on a suitable reformulation of the Linear Sampling Method (LSM). The LSM is a reliable and computationally effective imaging approach, which is exactly cast as a linear inverse problem (i.e., no approximation is required). This is made possible by restricting the processing task to the reconstruction of the shape of the anomaly and neglecting the retrieval of the electromagnetic features. Since the LSM has been never applied to the imaging of magnetic targets from electric field data, a preliminary assessment of its reconstruction capabilities towards purely magnetic anomalies is given by means of numerical examples.
