| Abstract: | The asymptotic waveform evaluation technique is an efficient for analyzing method wide-band electromagnetic scattering. In this paper, the asymptotic waveform evaluation technique is applied to the method of moments to compute the radar cross section of two-dimensional random dielectric objects. The numerical results are in good agreement with the results obtained by the method of moments at each frequency. The computational efficiency is improved greatly. |
