摘要
为了丰富火成活动及热演化历史研究所需的时间序列数据,在协同分析明安图射电日像仪(Mingantu ultr-awide spectral radio heliograph,MUSER)月球微波探测数据和月球微波辐射计(microwave radiometer,MRM)数据的基础上,建立了新的地基对月观测手段.此外,从月表瞬时亮温分布模拟和亮温数据在二维瞬时坐标系投影2个角度出发,建立三维月球浅表层亮温时空变化模型,并通过解析月固坐标系与观测时刻瞬时投影坐标系的转换关系,明确地基观测场景下月表亮温三维分布球面到二维瞬时投影面的精确变换,实现射电日像仪地基观测过程中月表亮温分布的数值模拟.
Based on the cooperative analysis of Mingantu ultrawide spectral radio heliograph data and lunar microwave radio-meter data,a new lunar observation method on earth is established to enrich the time series data of lunar igneous activity and thermal evolution history.In addition,a three-dimensional lunar surface brightness temperature time-space change model is developed from two aspects including the transient brightness temperature distribution simulation and the projection of brightness temperature in two-dimensional instantaneous coordinate system.The accurate transformation of lunar brightness temperature from three-dimensional distributed sphere to two-dimensional instantaneous projective plane at the observation scenario is identified by analyzing the rotation matrix of the moon-fixed coordinate system and the instantaneous projection coordinate system.This research achieves the numerical simulation of lunar brightness temperature distribution at the observation scenario.
