Contactless Microwave Tomography via MIMO GPR

This paper presents an imaging approach for Multiple Input Output Ground Penetrating Radar (MIMO GPR) systems working in down-looking contactless mode. The exploits a linear approximation of the scattering phenomenon and is based on ray-based propagation model, which takes into account presence air-soil interface. Accordingly, Interface Reflection Point concept extended to case MIMO GPR. proposed performs 2D scalar applies Truncated Singular Value Decomposition regularization scheme perform inversion. effectiveness assessed by processing synthetic real data. data are referred lunar soil have been collected means Lunar Regolith Radar, installed Chang’E-5 lander.
