摘要
本文利用Lomb-scargle周期图算法对中山站高频雷达探测的极区中层目标回波信号的时间序列进行了周期性分析和研究。结果表明,在不同年份探测的极区中层目标回波中,均出现了显著的半日周期分量,且其置信度均大于99%。本文的工作为中山站高频雷达探测极区中层目标回波的运行模式提供一定的参考。
In this paper, the periods characteristics of Polar Mesosphere Summer Echoes（PMSE） observed by Zhongshan SuperDARN radar have been analyzed using Lomb-Scargle periodiag algorithm. The result shows that there are obvious semi-diurnal periods for PMSE observed in different years and the confidence levels are greater than 99% in all cases. The efforts of the paper can be used as certain reference for the operation mode of observation of PMSE by SuperDARN radars.
