Scientific paper

Earth-based images of Venus obtained with the Arecibo 12.5 cm radar in 1975 and 1977 with resolutions of 10 and 5 km, respectively, are discussed. The average scattering law of the planet was divided into the data to yield the ratio between the received power from a particular area and that expected for a homogeneous surface having the same average properties as are observed for Venus. Mercator projections covering regions in the vicinity of the Alpha and Beta features are given. The images studied show a diverse surface terrain, probably produced by both impact events and tectonic activity. Only a small number of craters are observed; however, relatively smooth surfaced craters may not be visible at the high incidence angle and relatively low signal-to-noise ratio of these images. Large-scale features display lineaments and parallel ridges possibly of tectonic origin. If, as suggested by Goldstein et al (1978), beta is of volcanic origin raylike features associated with it may be flows or approximately radial fractures similar to those in the Tharsis region on Mars.
