In this paper, after a brief outline of the Robin boundary condition iteration (RBCI) method for the finite element solution of two‐dimensional electromagnetic scattering problems in open boundaries, a fast post‐processing procedure is described for the computation of the bistatic radar cross‐section based on the development of the scattered field in series of cylindrical harmonics. Moreover by utilizing the same series a scalar indicator is derived for estimating the accuracy of the numerical solution. Application examples are also provided.
