摘要

Abstract

Ionospheric scintillation is a physical phenomenon affecting radio waves caused by irregularities in the ionospheric electron density.Radio signals passing through ionospheric irregularities exhibit random and rapid fluctuations in amplitude and phase,thus disrupting the transmission of radio signals.Particularly for Global Navi-gation 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 cal-culation method of GNSS scintillation indices and focuses on analyzing the current research status of scintillation detection methods.The manual visual detection method,threshold detection method and non-scintillation index de-tection 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 different application scenarios.
