Radio-frequency (RF) tomography is extended for imaging underground structures and tunnels assuming rough terrain.
The theory of RF tomography described in an earlier paper remains applicable, provided that a numerical Green’s function is computed. An FFT-based and intrinsically parallel method for obtaining numerical Green’s functions is described. This method
is corroborated with explicit formulas and implemented for RF tomography. Simulated data computed using a finite-difference
time-domain code are used to demonstrate performance.
