短波通信实际上是天波通信,而天波通信中,电波比较深入地进入电离层,因此受电离层变化的影响较大,信号很不稳定,即使按常规选择频率,同时确保天线方向架设的准确,有时仍然会发生收不到信号、信号时强时弱及受其他信号干扰等现象。为此短波自适应跳频技术的出现,较好地解决了短波通信质量受电离层变化及其他干扰的影响,使短波通信质量有了提高。
Shortwave communication is actually skywave communication, and skywave communication, the radio waves into the ionosphere more deeply, so the greater impact of changes in the ionosphere, the signal is very unstable, even if the conventional choice of frequency, while ensuring that the antenna orientation erection accuracy, Sometimes still can not receive the signal, the signal is strong and weak and affected by other signals and other phenomena. Therefore, the emergence of shortwave adaptive frequency hopping technology solves the problem that the quality of shortwave communication is affected by ionospheric variations and other interferences, and the quality of shortwave communication is improved.
