Calculation of the Height-Time Dependence of the Electron Density of the Ionospheric Plasma Under Instability of the Incoherent Scatter Radar Constant

Methodological features of calculation the electron density of the ionospheric plasma using the critical frequency (frequency of reflection from the maximum of the ionospheric F2 layer). To obtain the critical frequency using the incoherent scatter radar constant, the level of background noise at its antenna input is analyzed.
