| 摘 要： | 介绍了波导传播条件以及目前用于计算波导传播特性的2种模型——抛物方程模型和射线追踪技术。利用抛物方程模型计算了波导环境下，电磁波在不同的发射频率、不同位置处的传播损耗，利用射线追踪技术模拟了射线在波导中的传播轨迹和时延特性。结合不同的计算结果，综合分析了大气波导传播特性对通信系统的影响。

| Abstract: | This paper introduces the duct propagation conditions and two models used for calculating duct propagation characteristic at present： parabolic equation model and ray tracing technology. The propagation loss of electromagnetic wave is calculated under different transmit frequencies and places with parabolic equation model ; the propagation trace and time difference of rays in duct is simulated with ray tracing technology. At last this paper generally analyses the effects of atmospheric duct propagation characteristic on communication system by combining with different results. |
