RCS Calculation of Electrically Large Targets on Sea Surface by Iterative MOM-PO Method

In this paper, a hybrid MOM-PO method is proposed to achieve reliable electromagnetic scattering modeling by taking the combination of ship target and reflector array as the analysis target, aiming at the characteristics of the target with strong scattering effect, clutter effect and local coupling. The simulation results show that the proposed method can obtain the relatively accurate calculation results of the scattered field and reduce the huge calculation time requirement for the large unknown quantity loop nesting.
