Abstract:

New equivalent edge currents and corner diffraction coefficients are obtained for the case of far zone bistatic scattering from flat plates. It is shown that the new solution does not contain the so-called false shadow boundaries found in previous high frequency solutions. The results illustrate that this solution gives good first-order results when compared with measurements, moment method calculations, and previous high frequency solutions. Keywords Ray theory, Electromagnetic scattering, Radar cross section.
