I step away softly, just as I creep here quietly I wave gently, sighing goodbye to the western sky.
轻轻的我走了，正如我轻轻的来；我轻轻的招手，作别西天的云彩。
The transmission of the sky wave is realized by the reflection from ionosphere, especially after reflecting many times, to achieve global communication.
天波的传播是利用电离层的反射来实现的，尤其是多次反射后可以实现全球通信。
Ionospheric frequency modulation causes spreading of the surface clutter in Doppler domain which greatly limits the detection performance of HF sky-wave radars.
电离层频率调制导致地表面杂波的多谱勒展宽，极大地限制了高频天波雷达的目标探测性能。
