| 摘 要： | 电磁波在不均匀大气中传播时会产生折射，导致其传播方向和传播速度发生变化。等效地球半径法被广泛应用于大气中电波传播的计算问题。文章介绍了等效地球半径的两种定义，讨论了两种定义的区别和联系及其应用局限，分析了电磁波在等效地球和真实地球上传播参数之间的关系及计算。

| Abstract: | The radio propagation in the uneven atmosphere will produce refraction,leading to propagation direction and velocity change.The method of equivalent earth radius is widely applied to solve the problem of radio propagation in the atmosphere.Two definitions of the equivalent earth radius were introduced,the difference and relationship between the two definitions were discussed and their applications limitations were also described,the parameters calculation and relationship of radio propagation in real earth ... |
