摘要
采用月球探勘者号(lunar prospector,LP)扩展任务段的视线加速度数据,利用最小二乘平差反演月球虹湾区域重力场。对解算结果进行残差统计和功率谱估计,并将解算得到的视线加速度模型与现有的高精度重力场模型SGM150j、GLGM3、LP150Q进行比较,验证了视线加速度方法精化局部重力场的可行性。结合虹湾地区地形,分析了该区域地形与重力异常之间的相关性。
Based on the least-squares method, the area of Lunar Sinus＇ gravity field is recovered using the line-of-sight acceleration data from Lunar Prospector extended mission. By counting the least-square residuals and calculating the power spectrum, as well as comparing the gravity model of line-of-sight with the high resolution gravity models, such as SGM150j, GLGM3, LP150Q, the feasibility and reliability of the line-of-sight method in improving lunar local gravity models is verified. The correlation between topography and gravity of Sinus is also briefly analyzed.
