摘要：

When analyzing object scattering, characteristic mode (CM) theory only focuses on the inherent properties of the target object and has nothing to do with any external factors. Different from traditional analytical eigenmode, characteristic mode method not only retains the advantages of clear theoretical concept of analytical eigenmode, but also combines the advantages of numerical method of moment (MoM) in dealing with irregular structures. Therefore the universality of the method is guaranteed. An aircraft example's analysis of radar cross section (RCS) using characteristic mode is given in this paper. The solution of characteristic equation can use implicit Arnoldi iterative algorithm. Characteristic mode theory provides theoretical support for the original antenna design so as to design an antenna with excellent performance.
