The classic analysis of high-frequency (HF) protection only takes account of the channel delay effect of HF signal, neglects the delay effect of electric traveling wave.
高频保护传统分析方法仅考虑高频信号在通道中的延时效应，没有分析电气量的行波延时效应。
The ionosphere contamination imposing on the High-frequency(HF) radar echoes has to be suppressed since it severely degrades the detection performance of HF radar.
高频雷达回波信号受到电离层污染从而影响了雷达的探测性能，因此需要进行去污染处理。
