A method of calculation of electron density profiles from h'(f) traces of vertical sounding

A necessity to develop a new method to calculate the electron density profiles has been vital due to inaccuracy when calculating the profiles through the widespread Huang-Reinisch method (including the one used at ISTP SB RAS) [1]. The algorithm we offer calculates electron density distribution in the middle ionosphere containing maximum in the E-layer (or without it) by height-frequency h’(f) traces of vertical sounding.
