Magellan

Magellan（专名或术语）

The Magellan spacecraft started radar photography of surface of Venus on Sep 15, 1990, using wavelengths in the cm range. It used synthetic aperture radar to reveal details as small as 120 meters across, increasing previous resolution by a factor of 10. The five year Magellan project involved the mapping of the whole surface of Venus, much like Mariner 9 mapped Mars in 1971 and 1972.

Magellan航天器于1990年9月15日开始使用厘米波段的雷达摄影技术对金星表面进行成像。它利用合成孔径雷达揭示出最小仅120米宽的细节，将分辨率提高了10倍。为期五年的Magellan项目涉及对金星整个表面的测绘，这类似于1971年和1972年Mariner 9对火星的测绘。
