An Efficient 3-D MoM-PE Hybrid Model for Scattering of the Key Target in A Large-scale Complex Environment

This paper presents a three dimensional hybrid model for predicting scattering fields from a key target in the large-scale environment. The Method of Moments (MoM) is used to compute the electromagnetic scattered waves from a target, and the bidirectional vector parabolic equation (PE) is used to consider the influence of complex factors such as topography, atmospheric duct, rain and fog,etc., on the scattering field in large-scale environment. The communication between the two algorithms is completed in the Target region. Through a typical example, the proposed hybrid method is verified by comparing it with the MoM, and the results are in good agreement.
