Abstract. A linear relationship between the
frequency shift and the change in the energy of the time-limited region of a
monochromatic radio wave is revealed due to its refraction during radio
transmission of the spherically symmetric gas envelope of the planet. The
method for detecting stratified structures in the atmosphere-ionosphere system
based on two-frequency radio transmission data is substantiated. The
application of the method for analyzing the radio occultation data of the
VENERA-15, -16 satellites indicated the existence of the lower region of the
Venus daytime ionosphere and revealed stratified periodic variations in the electron
number density with a vertical scale of 6 km in it.
Keywords: radio wave propagation,
occultation of ionosphere.
