【摘要】：基于嫦娥系列卫星微波辐射计数据的月壤厚度反演是中国月球科学研究的重要目标之一。基于辐射传输方程,数值模拟了不同频率、(FeO+TiO2)含量和表面温度条件下厚度对月壤微波辐射亮温的影响;基于嫦娥二号卫星微波辐射计(Chang’E Lunar Microwave Sounder,CELMS)数据,结合Apollo计划获取的月壤厚度资料及其他月壤厚度资料,系统分析了厚度对CELMS观测数据的影响。结果表明:频率、(FeO+TiO2)含量、表面温度对亮温的影响远大于厚度对亮温的影响,是基于CELMS数据进行月壤厚度反演的重要影响因素;低频、低(FeO+TiO2)含量、低温条件下,厚度对CELMS数据的影响最大;利用3 GHz、凌晨时刻的CELMS数据进行月陆地区月壤厚度反演可行。研究结果对基于嫦娥系列卫星CELMS数据的月壤厚度反演具有重要参考意义。
[Abstract]:The inversion of lunar soil thickness based on the data of Chang'e series satellite microwave radiometer is one of the important targets of lunar scientific research in China. Based on the radiative transfer equation, the effects of the content of Feo TIO _ 2) at different frequencies and the surface temperature on the brightness temperature of lunar soil microwave radiation are numerically simulated, and based on the Chang 'e-2 satellite microwave radiometer Chang'e Lunar Microwave Sounder Lunar Microwave CELMS, Based on the lunar soil thickness data and other lunar soil thickness data obtained from the Apollo program, the influence of the thickness on the CELMS observation data is analyzed systematically. The results show that the influence of frequency content and surface temperature on brightness temperature is much greater than that of thickness on brightness temperature, which is an important factor in the retrieval of lunar soil thickness based on CELMS data, low frequency, low Feo TIO _ 2 content and low temperature. The thickness has the greatest influence on the CELMS data, and it is feasible to use the CELMS data of 3 GHz, early in the morning to retrieve the lunar soil thickness in the lunar land area. The results are of great significance for the inversion of lunar soil thickness based on Chang'e series satellite CELMS data.
