The present paper is concerned with methods and algorithms of the software system for the automatic interpretation of radio physics information, as acquired by an FMCW ionosonde (at the Institute of Solar-Terrestrial Physics, Siberian Branch, Russian Academy of Sciences), which provides for vertical sounding (VS) and oblique sounding (OS) of the ionosphere. The following problems were considered within this problem:
preprocessing to suppress noise from images and improve amplitude characteristics
data compression using a cellular automaton
interpretation of VS and OS ionograms.
The method of interpreting ionograms is based on using simulation data for the frequency dependences of the long-term prediction propagation characteristics and the results of processing experimental data.
