超视距传播，超越地平线传播
双语例句
- Beyond-the-horizon detection of targets at ranges of thousands of kilometers can be achieved by Sky-wave Over-the-horizon Radar ( OTHR) operating in the high-frequency band. This very long coverage is obtained by using sky-wave propagation, which is, reflecting the radar signal from the ionosphere.
工作在短波波段的天波超视距雷达可检测到地平线以下相距上千公里的目标，这样远距离的探测是通过电离层对雷达电磁波反射来实现的。
