| 摘 要： | 本文联合运用几何光学和等效电磁流法,导出了金属反射面轴向散射场和雷达截面(RCS)的简洁表达式,研究了从旋转二次曲面(凹面或凸面)中寻找具有最低RCS值的曲面形状优化方法,给出了一个典型实例的单站RCS立体分布图,以及最低RCS值所对应的波谷曲线和最佳表面参数。

| Abstract: | The simple calculation formulas for nose-on scattering field and radar cross section of reflectors are derived, where the specular field is obtained by the mothod of Geometrical Optics and the edge-diffracted field by the method of equivalent currents. Optimization of some rotational two-order curved convex or concave surfaces with lower RCS value are investigated. A typical example is given with spatial RCS graphcs and lowest RCS value. Optimum surface parametres are obtained. |
