RADIO ASTRONOMICAL OBSERVATIONS OF VENUS WITH HIGH RESOLVING POWER,

Abstract

During October-November of 1962 observations were carried out of the radio emission from Venus on 3.02 cm wavelength by means of a large Pulkovo radio telescope with a variable profile antenna. The purpose of these investigations was to evaluate the nature of the distribution of radio brightness, by using high resolving power and high precision of the coordinate measurements with a variable profile antenna. A divergence between the optical and radiomethods cannot be explained by the presence of high radiation belts as in the case with the Jupiter. Radio emission is practically absent at a distance of 1.07R from the center of the disk of the planet, i.e. the height of the radiation region does not exceed 420 km above the cloud cover of Venus. The results of measurements of the effective dimensions of Venus are shown. An attempt to determine the phase variations of radio temperature with displacement of the center of gravity of radio emission led to a negative result. The observations agree best of all with the model of a hot surface and cold atmosphere.
