【摘要】：由中国"嫦娥一号"(CE-1)微波辐射计对月球虹湾地区观测时刻相对应的太阳入射角与方位角,由极点球面坐标系与月球观测点局部坐标系的转换关系,得到CE-1对月球虹湾区域(Bay of Rainbow,拉丁文Sinus Iridum)观测的当地时间.采用CE-1微波辐射计观测数据,得到月球虹湾地区当地不同时间的辐射亮度温度(Tb)变化分布.由月表三层模型的热辐射传输理论,结合CE-1微波辐射计19与37GHz通道的Tb数据,反演得到月球昼夜不同时段虹湾地区表面月尘层与月壤层的物理温度变化,分析了影响虹湾地区月表面物理温度的主要因素.
[Abstract]:The solar incident angle and azimuth angle corresponding to the observation time of the lunar rainbow bay area are measured by the Chinese "Chang'e-1" (CE-1) microwave radiometer, and the transformation relationship between the polar spherical coordinate system and the local coordinate system of the lunar observation point is obtained. The local time of CE-1 observation of (Bay of Rainbow, Latin Sinus Iridum) in Lunar Rainbow Bay is obtained. Based on the observation data of CE-1 microwave radiometer, the variation distribution of radiance temperature (Tb) at different time in Hongwan area of the moon is obtained. Based on the thermal radiation transmission theory of the three-layer model of lunar table and the Tb data of CE-1 microwave radiometer 19 and 37GHz channel, the physical temperature changes of lunar dust layer and lunar soil layer on the surface of Hongwan area in different periods of day and night are obtained. The main factors affecting the monthly surface physical temperature in Hongwan area are analyzed.
