Electromagnetic Scattering and Parametric Models of Curved Surface in High-frequency Region

With the development of radar stealth technology, electromagnetic scattering has been widely used, and the strong scattering center of military targets has been effectively suppressed by various means. At this time, the secondary scattering becoming more and more important. In this paper, the scattering field of two-dimensional perfect conductive cylinder was studied, and the curved surface diffraction field is mainly investigated. Further more, the parametric model of the curved surface diffraction field is given by function fitting method. Combined with examples, the importance of secondary scattering in high frequency region is demonstrated and the accuracy of the parametric model derived in this paper is verified.
