It is crucial to overcome the limitation of the computer capacity in analyzing the electromagnetic (EM) scattering from electrically large objects. The characteristic basis function method (CBFM) is a novel approach to solve this problem. In this paper, a more efficient method is presented by combining CBFM with the parallel technique. The matrix used in CBFM is rearranged to be suitable for parallel process. The parallel CBFM is applied to analyze the electromagnetic scattering feature of 3-D objects. The obtained results confirm the accuracy and efficiency of the proposed method in speeding up the RCS calculation of large scale objects.
