This paper proposes an efficient hybrid sparfied adaptive cross approximation-multilevel fast adaptive cross approximation-characteristic basis function method (SPACA-MLFACA-CBFM) method for solving electrically large PEC targets. In this method, the CBFM is used to reduce the number of unknowns. The SPACA-MLFACA is employed to compress the reduced submatrices associated with the far-blocks pairs. Numerical results show that the new method can save much memory than the conventional MLFACA-CBFM.
