Efficient analysis of complex onboard antenna with large-scale platform by combining preprocessed data with hybrid MoM-PO method

Abstract

A new and general hybrid scheme consisting of the method of moments (MoM) and the physical optics (PO) is presented for the efficiently modeling of complex antennas installed on large-scale platforms. Different from the conventional MoM-PO, the proposed general hybrid technique is more flexible to handle arbitrary onboard antennas by integrating preprocessed data of antennas into the hybrid scheme. With this new hybrid technique, we can conveniently predict the disturbed onboard antenna performance even without the detailed configuration of the antenna. Numerical results show good efficiency and accuracy of the proposed hybrid technique.
