GPR Imaging as an Inverse Problem: What Is the Real Added Value?
Ground-penetrating radar (GPR) is a diagnostic tool well assessed in a variety of areas, including geophysics, archaeological prospection, civil engineering, and planetary exploration, just to mention a few examples.
Notwithstanding the simplicity of the underlying principles, a significant limitation of GPR relates to the interpretability of the raw data, presented under the form of radargrams, particularly in challenging scenarios.
To enhance the interpretability of the raw data, it is necessary to reliably model the electromagnetic scattering, so that the radar imaging is conceptualised as an inverse scattering problem. For such an inverse problem, the geometric and electromagnetic properties of the targets are retrieved by the field scattered by the target when an incident field impinges on it. Despite the simplicity of the underlying principles, this inverse problem is inherently complex due to its non-linear nature and ill posedness.
In this webinar, Dr Francesco Soldovieri will present the microwave tomography, based on linear models of the electromagnetic scattering, under a unified mathematical framework able to account for arbitrary measurement configurations and background scenarios. Furthermore, the investigation of the reconstruction performance of the microwave tomography for different measurement configurations and background scenarios will be presented. Finally, several application cases will be shown.
