Observations of the surface of Venus, carried out by the Pioneer Venus radar mapper at a wavelength of 17 centimeters, reveal a global mean reflectivity at normal incidence of 0.13 +/- 0.03. Over the surface, variations from a low of 0.03 +/- 0.01 to a high of 0.4 +/- 0.1 are found, with Theia Mons, previously identified as possibly volcanic, showing a value of 0.28 +/- 0.07. Regions of high reflectivity may consist of rocks with substantial inclusions of highly conductive sulfides.
先驱者金星雷达测绘器在 17 厘米波长处对金星表面进行观测，发现其在正入射时的全球平均反射率为 0.13 +/- 0.03。在金星表面，从低至 0.03 +/- 0.01 到高至 0.4 +/- 0.1 的变化都有发现，其中先前被认为可能是火山的 Theia Mons 地区的反射率为 0.28 +/- 0.07。高反射率区域可能由含有大量高导电硫化物的岩石组成。
