| 摘 要： | 凹槽散射是开口腔结构的一种典型代表。用复射线方法十分简便地实现了凹槽结构散射宽度的预估，并用ＧＴＤ理论对复射线场在入射口面边缘上的绕射场贡献作了简化处理，计算结果与射线模式法所得结果吻合较好，但简化算法却可节省大量计算机时间。

| Abstract: | Trough scattering is a typical open-ended cavity problem.In this paper,the comples raymethod is used to analyze the radar echo width(REW)of a trough structure,and the geometrical theory of diffraction(GTD)is employed to deal with the diffracted contribution from the trough edges.The results obtained hereby agree well with those from the ray mode method,but the simplified method may save a lotof computer time. |
