摘要

我们介绍了2015年3月20日日食期间在欧洲观测到的TEC变化的超宽带信号的对比分析结果。在一些欧洲城市检测到波浪扰动，其周期为50 - 60分钟，持续时间为120 - 180分钟。它们的振幅为0.8 - 2 TECU，并与赫斯特指数值呈正相关。所有分析信号的分数带宽为0.67 - 1.14。所得结果与非相干散射和垂直测深结果吻合较好。

Observations of Ultrawideband Signals in GPS TEC Variations Over Europe During Solar Eclipse

We present the results of comparative analysis of ultrawideband signals observed in TEC variations over Europe during the solar eclipse of 20 March 2015. Wave disturbances over a number of European cities are detected which have periods of 50 - 60 min and durations of 120 - 180 min. Their amplitudes are of 0.8 - 2 TECU and exhibit positive correlation with Hurst exponent values. The fractional bandwidth is of 0.67 - 1.14 for all analyzed signals. Obtained results agree closely with those from incoherent scatter and vertical sounding techniques.
