| 摘 要： | 利用Lunar-Prospector扩展任务的视线加速度数据,根据点质模型恢复了月球近区的重力场,将其与LP165月球重力场模型进行了比较和分析,并利用恢复的重力场联合月球地形数据对Mas-con进行分析,总结了月球重力场的主要特征及其研究方向发展趋势,将重力场恢复技术与我国的探月计划-"嫦娥"工程结合起来,为建立高精度的月球重力场和地形模型提供了一种有效而实用的方法。

| Abstract: | Based onthe theory of mass-point, the near-side lunar gravity is recovered by using light-of-sight data of Lunar-Prospector extend task.The result has been compared with LP165 lunar gravity model, and the Mascon has been analyzed with the combination of gravity and topography data.At the same time, the characters of lunar gravity and its development trend are summarized.By combination of gravity recovery technique with China's moon exploration project-"Chang’e", a practical and effective method for acquiring a high accuracy lunar gravity and topography model is provided. |
