Short-pulse scattering from buried wires and bodies of revolution

The method of moments is used to analyze short-pulse plane- wave scattering from perfectly conducting thin wires and bodies of revolution buried in a lossy, dispersive half space. The analysis is performed in the frequency domain, with the time-domain fields synthesized via Fourier transform. To make this analysis efficient, the method of complex images is used to compute the frequency-dependent components of the half-space dyadic Green's function. Results are presented for short-pulse scattering from buried wires, spheres and cylinders, using measured frequency- dependent soil parameters (permittivity and conductivity), and the phenomenology associated with the scattering is investigated in detail.
