Microwave emission of the Moon, measured by the Chang’E-2 Microwave Radiometer (MRM), provides an effective way to understand the physical properties of lunar near-surface materials. The observed microwave brightness temperature is affected by near-surface temperatures, which are controlled by the surface albedo, roughness, regolith thermophysical properties, and the high thermal inertia and permittivity of both surface and buried rocks. In this study, we propose a rock model using thermal infrared measurements from the Lunar Reconnaissance Orbiter's (LRO) Diviner as surface temperature constraints. We then retrieve the volumetric rock abundance (RA) from nighttime MRM data at several rocky areas. Although our retrieved MRM RA cannot be compared to the rock concentration measured with LRO Camera images directly, there is a good agreement with Diviner-derived RA and radar observations. The extent of several geological units, including rocky craters, hummocky regions, and impact m...

利用Chang娥二号微波和分频器数据反演月球表面和地下岩石丰度

用Chang'E-2微波辐射计（MRM）测量的月球微波发射，为了解月球近地表物质的物理特性提供了有效的方法。所观察到的微波亮度温度受近地表温度的影响，近地表温度受地表反照率，粗糙度，硬质岩热物理性质以及表层和埋藏岩层的高热惯性和介电常数的控制。在这项研究中，我们提出了一个岩石模型，该模型使用月球侦察轨道器（LRO）Diviner的热红外测量作为地表温度约束。然后，我们从多个岩石区域的夜间MRM数据中检索体积岩石丰度（RA）。尽管我们无法将检索到的MRM RA与直接用LRO摄像机图像测量的岩石浓度进行比较，与Diviner衍生的RA和雷达观测有很好的一致性。几个地质单元的范围，包括岩石火山口，山岗地区和撞击地带。
