Radar Cross Section of General Three-Dimensional Scatterers

Allen Taflove, K. Umashankar

Abstract

Two disparate approaches̲the finite-difference time-domain (FD-TD) method and the method-of-moments (MOM) surface -patch technique-which permit highly realistic modeling of electromagnetic scattering problems are compared. New results of induced surface currents and radar cross section are presented for an important three-dimensional canonical cube scatterer. It is shown that a high level of agreement for the two modeling approaches is obtained for this scattering example.
