自然环境对短波通信的影响

The affection of the natural environment on HF communication

自然环境的变化直接影响短波通信的质量。首先简述了短波通信的特点,分析电离层变化的主要特点和规律,介绍了电离层变化和多径传播对短波通信的影响,进而提出增强短波通信可靠性、有效性的相应措施和技术,对了解短波通信的环境和有效应用短波通信具有重要意义。

The variety of the natural environment will influence the quality of HF communication di- rectly. This paper states the specialty of HF communication, and analyses main characteristic and disciplinarian of the ionosphere change. The affection of the ionosphere change and many path on HF communication is introduced. At last,corresponding measures and techniques to improve the HF communication reliability and validity are put forward. It is important for us to learn the environment of HF communication and to apply HF communication efficiently.
