本文用一组复源点产生的高斯波束来拟合入射的局部均匀平面波
根据复射线理论和一致性绕射理论
得出了求解二维圆柱形凹反射面的散射场和雷达截面积(RCS)的理论公式
给出了水平和垂直极化时的计算结果
并与其它方法所得结果进行了比较。
The incident plane wave is expanded as a set of Gaussian beams. Then
the theoretical analysis for a two-dimensional concave reflector is completed and the formulae of scattering field and radar cross section are derived by means of complex ray tracing and paraxial approximation respectively
combined with the uniform theory of diffraction. The numerical results are obtained for both horizontal and vertical polarezations. The results from complex ray theory agree very well with those from Geometrical Optics.
