【摘要】:由中國"嫦娥一號"(CE-1)微波輻射計對月球虹灣地區(qū)觀測時刻相對應(yīng)的太陽入射角與方位角,由極點球面坐標(biāo)系與月球觀測點局部坐標(biāo)系的轉(zhuǎn)換關(guān)系,得到CE-1對月球虹灣區(qū)域(Bay of Rainbow,拉丁文Sinus Iridum)觀測的當(dāng)?shù)貢r間.采用CE-1微波輻射計觀測數(shù)據(jù),得到月球虹灣地區(qū)當(dāng)?shù)夭煌瑫r間的輻射亮度溫度(Tb)變化分布.由月表三層模型的熱輻射傳輸理論,結(jié)合CE-1微波輻射計19與37GHz通道的Tb數(shù)據(jù),反演得到月球晝夜不同時段虹灣地區(qū)表面月塵層與月壤層的物理溫度變化,分析了影響虹灣地區(qū)月表面物理溫度的主要因素.
[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.
