Abstract

In the approximation of a strongly refractive medium, we solve the inverse problem of subsurface-radar imaging of buried inhomogeneities using data of multiposition ultra-wideband radio sounding. The fast Fourier transform is used for synthesizing a large aperture with focusing. A mathematical model of the proposed subsurface-imaging system is presented and its accuracy is estimated. The feasibility of the proposed method is confirmed by numerical simulations and model laboratory experiments.
