利用人工神经网络重构区域电离层临界频率分布
The critical frequency of ionosphere at linearity condition and the atmospheric refractive index formula are derived.
通过对线性条件下电离层临界频率和大气折射率公式的推导,并结合电离层电子浓度经验分布模型对电子浓度和大气折射率进行数值模拟,进而对电离层大气折射率的高度剖面图及其变化特性进行了分析,为微波卫星链路传播提供了理论参考。
This paper emphasizes on reconstructing ionosphere and wants to speculate on thesequential Real-time distribution of F2-layer s critical frequency foF2 in limitregions by making use of the parameters from nine observation stations on mainland China.
本文研究的重点是电离层重构,主要目的是利用当前国内9个垂测站的数据,推测F2层临界频率foF2在大面积区域连续的实时分布。
