Technique of ionospheric parameters automatic determination from data of vertical sounding with a continuous chirp signal

Solar-Terrestrial Physics
We present a technique for determination of ionospheric parameters based on automatic interpretation of vertical sounding (VS) ionograms. Ionograms are interpreted using points with significant amplitude, which were detected after secondary data ...

Quantitative explanation of satellite ionograms taken within the F 2-layer maximum

, 2020
. A quantitative explanation of ionograms taken within the F 2-layer maximum is presented. An assumption is made that there exist sharp horizontal irregularities of the electron density. There are ray trajectories which return back to the satellite after

Quantifying Errors in the Midpoint Transform Applied to Oblique Ionograms

It is important to specify the state of the ionosphere for Over‐the‐Horizon communications and surveillance. Both vertical and oblique ionograms provide valuable data to this end.

Automatic scaling of F2-layer parameters from ionograms based on the empirical orthogonal function (EOF) analysis of ionospheric electron density

, 2007
In this paper we apply a method based on empirical orthogonal function (EOF) analysis to automatically scale the F2-layer parameters obtained from ionograms.
