The algorithm of obtaining ionograms of oblique sounding of wideband radio channels was implemented in software. The paper presents an algorithm of computer fi ltering of ionograms with the use of median equalization. The algorithm of determining signal-to-noise ratio in HF ionospheric radio channel was developed and implemented in software.
