月球卫星遥感的目标是研究月球表面特征、内部结构及其演化历史。根据Clementine UV/维斯数据评估了虹彩窦中TiO 2和FeO的含量。地质地层单位和板条箱是基于空间分辨率高达10 m的SELENE地形相机（TC）图像进行可视化解释的。根据火山口的大小-频率分布，计算了不同地层单元的地质时代。重力异常是由SELENE重力模型（SGM 90d）生成的，以显示其与Mare Imperial的差异。此外，还利用嫦娥一号卫星的微波辐射计数据反演了月壤厚度。综合这些结果，可以看出虹湾与Imperdum海在内部结构和表层沉积作用上存在着明显的差异。描述了它的沉降、沉积、火山作用和撞击史。遥感地质分析对今后在潜在的虹湾软着陆和取样具有重要意义。
The objectives of lunar satellite remote sensing are to study lunar surface characteristics, inner structure, and its evolution history. The contents of TiO2and FeO are assessed from Clementine UV/VIS data for Sinus Iridum. The geologic stratigraphic units and crates are interpreted visually based on SELENE Terrain Camera (TC) images and the spatial resolution of which is up to 10 m. And the geologic ages of different stratigraphic units are calculated by the crater size-frequency distributions measurements. The gravity anomaly is generated from SELENE gravity model (SGM90d) to show its difference from Mare Imbrium. Furthermore, the thickness of lunar regolith is also derived from microwave radiometer data of Chang’e-1 satellite. Integrating these results, it shows that the Sinus Iridum is different from the Mare Imbrium in inner structure and surface sedimentation. And its history of subsidence, deposition, volcanism, and impact is described. It makes sense to the future soft-landing and sampling at potential Sinus Iridum by remote sensing geologic analysis.
