| 摘 要： | 电波信号穿过电离层传播时,由于电离层的作用将使得电波信号产生一系列的失真.分析了传统混沌时间序列预测的理论和方法,并分析了电波信号穿过电离层的时间序列特征,发现该时间序列具有混沌时间特征,进而在传统的混沌时间序列预测的基础上,给出了一种更适合于电离层电波衰减时间序列预测的方法.同时,利用它预测了一组电波信号穿过电离层的时间序列特征,并分析了其预测精度.结果表明,利用修正的混沌时间序列预测方法预测的电波信号穿过电离层衰减的时间序列,其短期的预测效果很好.

| Abstract: | The traditional method of prediction the chaotic time series and the time series characteristics of radio signal propagates through the ionosphere was theoretically analyzed respectively,and it is found the latter has the characteristic of the chaotic time series.Then,a more suitable time series prediction method of radio wave propagation through the ionosphere is given.On this basis,a set of attenuate amplitude time series radio signals which propagate through the ionosphere is predicted,and its prediction accuracy is analyzed.The results showed that the amplitude attenuation chaotic time series prediction by the modified method for the radio wave propagates through the ionosphere is very good at the short-term. |
