摘要

合成孔径雷达(SAR)的对焦既可以基于精确的星历数据，也可以通过自动对焦过程来实现。对于麦哲伦项目，这样的决定必须在麦哲伦SAR系统设计的早期阶段做出。气压计需求的分析是复杂的。作者通过分析得出结论，麦哲伦号导航系统获得的球风数据具有足够的精度，可以满足麦哲伦号图像分辨率的要求。

An Analysis Of The Focusing Performance Of Magellan Sar Image Data

Synthetic aperture radar (SAR) focusing can be achieved either based on accurate ephemeris data or on an autofocusing process. For the Magellan project, such a decision must be made in the early phase of Magellan SAR system design. The analysis of the emphemeris requirement is complicated. The analysis given by the author leads to the conclusion that empheris data obtained from the Magellan navigation system provide sufficient accuracy to meet the Magellan image resolution requirement.
