Advantages of Electromagnetic Interferometry Applied to Ground-Penetrating Radar: Non-Destructive Inspection and Characterization of the Subsurface Without Transmitting Anything

Ground-penetrating radar (GPR) is a non-destructive method that images the subsurface using radar. A transmitter generates a radar pulse. This signal propagates into the ground where it reflects against subsurface heterogeneities, and travels back to the surface. A receiver records the reflected signal. The reflected signal contains information...
