| الوصف: | COSMIC GPS Radio occultation systems are developed for investigating global ionospheric and tropospheric features of atmosphere ionospheric effects are a major critical concern in radio communications and navigation systems. The predominant ionospheric effect is scintillation, which causes small scale fading in GNSS received signals. Hence, there is a necessity to understand the ionospheric morphology, especially in low latitude region. In this paper, GPS RO ionospheric scintillation measurements over the Indian region have been considered for the analysis. A Novel spectral analysis tool based on synchrosqueezing transform (SST) method is proposed for identifying low latitude equatorial Ionospheric anomalies. It is found that SST provides better time-frequency resolution under conditions of severe scintillation. |
