Influence of Ionospheric Sporadic E on Radio Propagation in HF and VHF Band

  • 摘要: Es层是存在于电离层中的电子密度非常高的偶发E层(Sporadic E),其电子密度可达常规E层的100倍.电离层Es能够反射原本穿透F层的VHF低频段(30~150MHz)无线电波,而且对HF高频段(10~30MHz)无线电波传播具有显著影响.运用垂测和斜测观测数据,研究HF频段Es层电波传播特征,得到了不同类型及不同高度Es层的衰减系数.根据f0Es的日变化规律,可得HF频段衰减系数的日变化规律,进而分析并得到Es层对短波传播的影响.不存在电离层Es时,通常无法通过电离层实现VHF超远距离通信.为了对VHF链路通过电离层Es的传播衰减进行定量分析,根据EBU多条链路的观测结果,拟合并建立了电离层Es衰减模型.将该模型、ITU模型和观测数据进行对比,发现本文建立的模型准确度更高.利用建立的模型,对电离层Es不同临频f0Es条件下接收信号场强和电压随传播距离的变化进行了计算,结果可为VHF链路设计及建立提供参考.
