通过高频射线解获得具有恒定表面阻抗的无限长圆柱体的雷达截面（RCS）。射线解以几何光学射线和两个表面波的形式提供了散射过程的物理图像。结果表明，圆柱体RCS中的表面波共振现象可以根据Regge极点或圆柱体的固有频率来预测。通过高频射线求解获得的圆柱体 RCS 的数值结果与本征函数结果非常吻合。还讨论了预测表面波谐振的条件。
The radar cross section (RCS) of an infinitely long circular cylinder with a constant surface impedance is obtained via a high frequency ray solution. The ray solution provides a physical picture of the scattering process in terms of a geometrical optics ray and two surface waves. It is shown that the surface wave resonanee phenomenon in the RCS of the cylinder can be predicted in terms of the Regge poles or the natural frequencies of the cylinder. The numerical results for the RCS of the cylinder obtained via the high frequency ray solution show excellent agreement with the eigenfunction results. The condition for predicting the surface wave resonance is also discussed.
