Abstract

This paper provides a detailed numerical comparison between two frequency-domain rough-surface scattering models for the reconstruction of a short carrier-free pulse in the time domain. The two scattering models are a Space-Harmonic Model (SHM) and a Full-Wave Model (FWM), both of which assume a sinusoidally corrugated scatterer. To facilitate a time-domain comparison of the scattering algorithms, a Fourier series method is used to sum the scattered harmonics of the incident pulse. Several graphical comparisons are presented for backscttering of a train of square pulses which has been band limited to correspond to an X-band short pulse. The respective algorithmic difficulties and relative computational efficiencies are also briefly discussed.
