Main goals of radio-occultation experiments in VENERA-D mission are formulated. It is shown, based on the results of radio-occultation experiments obtained earlier with high potential radio-links in the Venusian gaseous envelop, that using variations of power and frequency at two coherent radio waves, one can study a fine structure of refracting medium which may bring fundamentally new information about the atmosphere-ionosphere system of Venus. Given the accuracy of data interpretation depends on different high-frequency subsystem performance characteristics, it is shown that the prime direction of the development, must be the balanced increase of the energy potential of radio links and improving the stability of the oscillators used. A novel technique of data interpretation applicable to high potential measurements in the ionosphere and atmosphere of the planet is discussed. Among all the other things the suggested technique makes it possible to see and study propagation of disturbances from the atmosphere into the ionosphere. Moreover, it is shown that the correlation between amplitude and frequency of signals which is underpinning the technique mentioned can be seen as an effective criterion of the validity of geometrical optics spherically symmetrical approximations for the inverse problem solution.
