一种短波频率预测方法及其实现

短波天波传播频率预测是短波天波通信电路性能预测的前提。在对当前短波频率预测方法进行分析的基础上,提出了一种天波传播最大可用频率预测的改进方法。并且,给出了该方法的程序框架设计及程序流程图,完成了系统的开发。最后,对该方法、REC533方法与手工作图法的预测结果进行了分析比较,证明了在国内范围内该方法能够得到比REC533方法更加准确的预测结果。

A Shortwave Frequency Prediction Method and its Implementation

The frequency prediction of skywave propagation in shortwave band is the precondition of performance prediction of skywave communication circuit.Firstly,this paper presents an improved prediction method of maximum usable frequency （MUF） of skywave propagation based on the analysis of the current shortwave frequency prediction method.Secondly,this paper presents the program frame design and flow chart to implement the software.Lastly,this paper analyses and compares the data result predicted respectively by this method,REC533 method and manual graphical method.It is proved that this method can obtain much more accurate prediction data than REC533 method in our country.
