Fast iterative MoM-PO hybrid method for complex onboard antenna array with large-scale platform

Abstract

A fast method of moments (MoM) - physical optics (PO) hybrid technique is proposed to fast analyze large and complex antenna arrays mounted on electrically large platform. In the fast MoM-PO method, the adaptive integral method (AIM) based on the MoM is combined with the PO and an iterative process is adopted to describe the interaction between the antenna array and the platform. Numerical results show that the proposed fast MoM-PO method can greatly reduce the CPU time and memory requirement compared with the conventional MoM-PO method.
