| 摘 要： | 月球表面辐射特性研究是月球探索的一个重要领域，对于勘测月球表面形态及进行资源勘探等具有重要意义，但是目前在月球表面直接进行近距离测量的数据非常少.本文建立了基于嫦娥三号着陆器地形地貌相机和缓释电机在轨遥测数据研究月球表面辐射特性的方法，初步测算得到嫦娥三号着陆区月球表面的太阳辐射光谱反射率为0.105，发射率为0.866.所得结果能够为进一步空间探测任务提供原始测算数据，以降低设计难度及提高探测能力.

| Abstract: | Emissivity and solar radiation reflectivity of the lunar surface are very important for mastering the lunar surface status and exploring resource. But it is very difficult to install special equipment on spacecraft to perform measurement near the lunar surface. Therefore until now there is very few direct measurement data. This paper had estimated emissivity and solar radiation reflectivity of the lunar surface based on thermal control coating parameters of topography camera and stepper motor which are mounted on Chang'E-3 Lander. Numerical results show that the reflectivity and solar radiation reflectivity at Chang'E-3 landing area are 0.105 and 0.866 respectively. This data could be consulted by further scientific research work. |
