The fast Fourier transform algorithm can be used as a highly efficient numerical means for the analysis of transient scattering phenomena. Examples illustrating the performance of this method are given for an incident pulse of Gaussian shape. It is noted that such a technique can best be exploited when additional characteristics of the radar system such as the actual transmitted waveform and the receiver transfer function are taken into account.
