The pulsed scattering by buried perfectly conducting cylinders is solved with the cylindrical wave approach. The source of the scattering problem is a wideband excitation from a plane-wave source field. A spectral approach is employed, expressing the electric field as a superposition of monochromatic contribution. Time-domain response is found through the inverse Fourier transform on the spectra relevant to each field contributions. Numerical implementation of the method turns out to be very accurate. The technique has important applications in the simulation of the scenarios of embedded objects within remote sensing techniques. Results are plotted to simulate both A-scan and B-scan plots typical of ground penetrating radar measurements. The method has been validated through a comparison with a numerical technique available in the literature.
