摘要
An improved calculation technique allowing the radar cross section computation of electrically large targets is presented in this paper. It is based on a hybridization technique combining the Geometrical Optics (GO) and the Physical Optics (PO) techniques. The GO technique takes high order interactions into account while the PO technique allows to get rid of caustics problems. The Physical Theory of Diffraction (PTD) is also implemented, in order to improve the accuracy and take into account the wedges diffraction of the target. This hybrid technique is well suited to compute the backscattered field from wind turbines illuminated by meteorological radars.
