| 摘 要： | 本文根据复射线法对通过介质天线罩的高斯波束场进行近轴近似分析。实空间的轴向复射线追综大大简化了计算过程,而复相位差、反射-传输系数和曲面扩散系数的进一步校正则提供了相当精确的结果。所得数字结果表明,在波束的近轴区域内为获得同样的计算精度,近轴近似法所需要的计算机时间远小于复射线追综法的时间。 |

| Abstract: | Based on complex ray method,a paraxial approximation analysis of Gaussian beam transmission through a dielectric radome is presented.Complex on-axis ray tracing in real space simplifies the computation processes greatly, and the corrections of complex phase difference,reflection-transmission coef- ficient and divergence coefficient provide very accurate results.Numerical computations show that paraxial approximation gives almost the same accuracy in the paraxial region as complex ray method but spends much less computer time. |
| Keywords: | geometrical optics ray theory Gaussian distribution radome approximation value numerical calculation |
