Abstract. We discuss advantages of using the L-band signal
transmitted from an on-board equipment in a dual frequency occultation
experiment. It is shown that a considerable ratio between plasma influence in
the L-band signal parameters and equipment noises provides high precision of
determination of Venus ionosphere parameters. Presented new method of plasma
layers detection makes possible to detect small variations in electron density
and reveals wave phenomena in the planets ionosphere during occultation.
Keywords: occultation, radio wave propagation, ionosphere and
atmosphere of planets.
