DETERMINATION METHOD OF THE NONUNIFORM IONOSPHERE ELECTRON DENSITY HIGH LEVEL PROFILE Russian patent published in 2017 - IPC G01S1/32 G01S13/95 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to radio engineering and geophysics, namely to means of monitoring the state of ionosphere and measuring its parameters using space vehicles of satellite radio navigation systems. According to the received radio signals from the navigation satellites at two coherent frequencies ƒ₁ and ƒ₂ the total electronic content of N_T in the nonuniform ionosphere is determined, its average value is calculated and the high level profile of the average electron density of the ionosphere is determined by using the iterative procedure for solving the inverse problem, then the small-scale fluctuations average square deviation of the total electronic content and the nonuniformities β_i ionosphere intensity, and then the small-scale fluctuations average square deviation high level profile of the electron concentration in the ionosphere nonuniformities is determined.

EFFECT: provision of the possibility to determine simultaneously the high level profiles of the average electron density and the small-scale fluctuations average square deviation of the electron density in the nonuniform ionosphere.
