电磁波在大气环境中传播受到各种因素的影响，引起电磁波出现异常传播现象，尤其在陷获折射条件下，形成大气波导传播。大气波导对电子系统武器装备的性能及战术使用带来影响。为在大气波导环境下更好地运用武器装备，在介绍了大气波导的分类基础上，分析了大气波导特征量对电磁波形成波导传播条件的影响，重点论述了大气波导对电子系统武器装备性能及战术使用的影响。

Electromagnetic wave can be affected by all kinds of factors when propagating in the atmosphere. These factors result in anomalous propagation, especially when there exists an equipments atmospheric duct in the condition of trap refraction. Atmospheric duct influences the performance and tactical use of electronic equipments. In order to use the equipments better in the condition of atmospheric duct, this paper introduces the classification of atmospheric duct, analyses influences of atmospheric duct eigenvector on forming conditions of atmospheric duct, discusses the effect on performance and tactical using of electronic systems.
