In view of the calculation of electromagnetic scatter for the complex object, the hybrid technology that combines physical optics (PO) with moment method (MOM) is investigated, which search for the way of the reduction computational time and memory requirement and the improvement the calculative precision. The multi-resolution pre-processing technology is introduced for the iterative problem during solving the problems by MOM, and the calculation examples are given. The results show that the calculation efficiency is improved in the same accuracy by the hybrid method of PO-MOM.
