Abstract. We have used direct simulation of occultation signal using a numerical calculation of the parabolic diffraction equation to analyze variations of signal intensity and phase along the line of trajectory of Venus satellite during an occultation experiment. As a result we have proved the liner relationship between variations of phase and intensity of the signal deformed by regular spherically symmetric ionosphere. It is shown that a coincidence between energy and non-energy parameters of a sounding radio wave proves reliability of the result obtained from inverse radio occultation problem.

Keywords: occultation, radio wave propagation, ionosphere and atmosphere of planets.
