Abstract

We present a method to determine spatial distribution of the ionospheric electron density based on data of vertical (VS), oblique (OS), and backscatter (BS) sounding with a continuous chirp signal. Initial data represent the results of automatic processing and interpretation of ionograms, from which we calculate the height-frequency characteristics (HFC) of vertical sounding in the points selected on the sphere. From HFC tracks, we determine the ionospheric parameters and calculate the electron density profiles. This allows reconstruction of electron density spatial distribution within the sector of backscatter sounding and the region of HF radio paths. The resultant ionospheric parameters are used to correct ionospheric model IRI.
