摘要
爬行波是非镜面散射问题中的一类重要问题,射线寻迹是求解爬行波散射贡献的关键环节。文中基于短程线的定义,结合自由曲线曲面几何造型技术,探讨了对任意凸曲面导体目标表面进行爬行波射线寻迹的方法。对可展面爬行波射线寻迹计算进行了讨论,计算结果与理论值吻合,证明了方法的有效性;在此基础上,对解析求解困难的非可展面的爬行波射线寻迹进行了计算。
Creeping wave is a sort of key problems of the nonmirror surface scattering.Ray path tracing on convex surface is an important step to solve the creeping wave scattering. Present an effective method of computing for ray path tracing on any convex surface,based on the definition of short-cut line.The convex surfaces are modeled by NUBRS. Several examples about developable surface or undevelopable surface are given to verify the validity of the method.On the basis of it,calculate the undevelopable surface creeping wave ray path tracing that is difficult for calculating.
