The detection of ionospheric layers in the daytime Venusian ionosphere at heights of 80-120 km using results of two-frequency radio-raying by Venera-15, -16

We propose a technique for analyzing radio eclipsing data. It permits reliable separation of influence of the noise, ionosphere, and atmosphere on radio-raying results. This enables more accurate research into mechanisms of the ionosphere formation. Ionized layers are shown to exist in the daytime Venusian ionosphere at heights of 80-120 km. The position of the ionized region lower boundary may vary from 80 to 120 km, and electron density gradients may change several times.
