天波传播 meaning in English

sky wave propagation

The muf and the possible maximum skywave field strength are calculated and are compared with the corresponding groundwave . and the conclusion is that the main propagation mode 200 kilometers on the sea is groundwave and the disturbance of skywave could be omitted
得出天波传播的最高可用频率、可能的最强天波场强，并与相应的地波场强进行了比较，阐明了海上200公里距离上的短波通信中电波主要是以地波的形式传播的，天波对地波通信的多径干扰问题可以忽略的结论。
The ionosphere is a complex medium , which is aeolotropy , asymmetry , dispersive and changes randomly with time . in order to improve the communication quality of the shortwave that depends on the ionosphere , we should have aknowledge of the current condition of the ionosphere in real time . the backscatter sounding of high frequency can diagnose the real - time channel characters for shortwave communication or hf radar , which is great assistant to shortwave communication and hf radar
电离层是随机时变,各向异性,非均匀、色散的复杂介质。为了保证依赖于电离层进行的短波通信质量,必须了解电离层的实时状态信息。高频返回散射探测可以实时监测与短波通信或高频天波雷达相关的天波传播信道的状态,对短波通信和天波雷达工作起了重要的辅助作用。
