In this paper, radar echo width (REW) of a 2-D PEC target with tow edges situated over a random rough sea surface is analyzed by a combination of hybrid Kirchhoff approximation, physical optics and physical theory of diffraction (KA-PO-PTD) methods. The results are compared with those of conventional method of Moments (MOM). The effect of the target-surface configuration and wind speed on the REW...
In this paper a new hybrid method is used to solve the electromagnetic scattering from a 2-D PEC target under 1-D random rough surface based on multipath scattering strategy and equivalence principle. In this procedure, the Kirchhoff approximation (KA) and the physical optics (PO) Method are applied to calculate equivalent currents on the rough surface and PEC target respectively. The mutual coupling...
