    Abstract

    A hybrid MLFMA-PO algorithm is developed for the bistatic radar cross section computation of electrically large objects modelled with the impedance boundary condition. Surface integral equation formulation of the problem is based on the resonance free self-dual integral equation by Yan and Jin. Accuracy of the solutions of the developed methods are studied for various surface impedance values.
