Abstract :
The following problems, specific for working of georadars in tunnels, are considered: modeling of reflections from walls of a tunnel and from a truck, diminishing of these parasitic reflections, modeling of a georadar, mounted on a tunneling machine of shielded type, sounding through reinforced concrete. Finite-difference method in time domain (FDTD) is used.
