摘要
分析了新乡观测到的VLF相位周期滑移现象,研究了产生相位周期滑移的原因,揭示了相位周期滑移的实质:VLF传播相位周期滑移是发生在日出或日落过渡期间一种特殊的多模干涉现象,它是由传播路径昼夜分界处的低电离层不连续性所引起的模转换干涉所造成的。
The phenomena of phase cycle slipping of VLF signals observed at Xinxiang is analyzed, and what reason arise this phenomena is investigated in this paper. The analysis results show that the phase cycle slipping of VLF signals is a special multi-mode interference effect during sunrise or sunset, and is a result mode conversion interference that arises from discontinuousness of low ionosphere at the boundaries of day and night in the propagation path.
