摘要
电离层闪烁是由电离层电子密度不规则性引起的无线电波的物理现象。穿过电离层不规则体的无线电信号会产生振幅和相位的随机快速起伏，从而破坏无线电信号的传输通道。对于全球导航卫星系统 (GNSS) 而言，电离层不规则体会导致卫星信号发生周跳，严重时会导致信号失锁。检测闪烁对于 GNSS 等天基应用至关重要。介绍了 GNSS 闪烁指数的计算方法，重点分析了闪烁检测方法的研究现状；然后讨论了人工目视检测法、阈值检测法和非闪烁指数检测法，并分析了机器学习在闪烁检测中的应用；最后针对不同应用场景，比较了各种电离层闪烁检测方法的优缺点。
Abstract
Ionospheric scintillation is a physical phenomenon affecting radio waves caused by irregularities in theionospheric electron density. Radio signals passing through ionospheric irregularities exhibit random and rapidffuctuations in amplitude and phase, thus disrupting the transmission of radio signals. Particularly for Global Navigation Satellite Systems (GNSS), ionospheric irregularities can cause satellite signals to drop out or even lose lock.The detection of scintillation is crucial for space-based applications such as GNSS. This paper introduces the calculation method of GNSS scintillation indices and focuses on analyzing the current research status of scintillationdetection methods. The manual visual detection method, threshold detection method and non-scintillation index detection method are discussed, and the application of machine learning in scintillation detection is analyzed. Finally,the advantages and disadvantages of various ionospheric scintillation detection methods are compared for differentapplication scenarios.关键词
