Variation of Electron Density in the D-Region Using Kunming MF Radar under Low Solar Activity
So far, the least is known about the D-region ionosphere out of the entire ionosphere due to the lack of a conventional detecting method and continuous data accumulation. Medium frequency (MF) radar is an important conventional tool for understanding the
