GSSR V RTLS 5 12.6-12.9CM RADAR SCALED ECHO POWER/ALT V1.0

The Goldstone Solar System Radar observations of Venus from 1972 until 1988 are included in this data set. The system operated at 12.6 cm up until 1977 operated at 12.9 cm. The data consist of radar scaled backscatter cross sections in image format and, in most cases, associated altimetry observations. The data were acquired over 52 separate observing runs. In total the observations cover the region between approximately 260 degrees (leftmost) east longitude to 30 degrees (rightmost) east longitude, within approximately 20 degrees of the equator. Backscatter data were acquired with opposite sense circular polarization with incidence angles typically less than 10 degrees. Associated altimetric data were acquired using a two or three station interferometric system. Data are presented in Mercator projection with degrees/pixel in longitude dependent on the individual data file.
