Linear frequency modulation experimental results made by Sanya Incoherent Scatter Radar on August 19-21, 2023

On August 19-21, 2023, we made three days continuous experiments using a 4-MHz linear frequency modulation waveform. Based on original IQ data, we first did pulse compression processing and obtained the signal-to-noise ratio (SNR). Then based on SNR and the incoherent scatter radar function, we further estimated the electron density. In this dataset, we put the SNR of August 21, 2023 and the estimated electron density on August 19-21, 2023 together. These observations can be used for high resolution investigation on ionospheric fine structures.
