A technique is described and results are presented for 39-cm radar investigations of the reflectivity of local areas in the equatorial region of the Venusian surface between 290 and 340 deg planetocentric longitude. Variations in the unit effective area of backscattering from different parts of the surface are examined by separating the signals reflected from those parts. Surface regions are observed whose two backscattering parameters simultaneously attained extreme values. It is found that the planetocentric coordinates of these regions are close to those of the anomalously reflecting regions designated as C2 and D3, which were previously observed by other methods and at other wavelengths. Based on the identification of the presently observed anomalously reflecting regions with C2 and D3, the rotational period of Venus is estimated to be about 243.06 days.
