The effect of atmospheric refraction on the energy distribution of a reflected signal on the surface of Venus
Abstract
An expression is obtained for the effective scattering surface in the case of the bistatic radar probing of Venus. This expression is then used to determine the distribution of reflectivity on the planetary surface for a typical satellite position. It is shown that atmospheric refraction leads to substantial changes of the angular characteristics of scattering and to a shift of the center of the region of interest. At small glide angles, when the satellite is near the radio shadow region, there occurs a noticeable brightening of the edges of that part of the Venus surface which is visible from the earth.
