Abstract

This paper presents a method to predict the bistatic Radar Cross Section (RCS) of electrically large objects covered by lossy electric and/or magnetic radar absorbing material (RAM). The proposed method use modified Physical Optics (PO) approximation and Physical Theory of Diffraction (PTD) to obtain the scattered field. The PO and PTD integrals are calculated by Stationary Phase Method (SPM) to reduce significantly the computation time in contrast with numerical integration techniques.
