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.
