基于SeaWiFS对月观测数据的月球辐照度模型分析

Analysis of lunar irradiance model based on the SeaWiFS lunar observations

由于月表没有风和流水的侵蚀,月球的反射特性十分稳定,非常适合作为传感器辐射特性监视和定标的参考光源。基于地基对月观测数据,研究人员提出月球辐照度模型。然而现有的模型精度有限,难以满足高精度的应用需求。基于SeaWiFS对月观测数据,对月球反射特性的影响因子以及现有的ROLO和MT2009这两种月球辐照度模型进行分析,为进一步优化月球辐照度模型提供借鉴。

As the unique natural satellite of the Earth,the Moon has been studied for a long time.Since the lunar reflectance is very stable due to the absence of water and atmosphere,the Moon is very suitable as a reference standard for radiometric calibration of on-orbit sensors.Based on the Earth-based lunar observations,the lunar irradiance models were developed.However,the precisions of the current models are limited.Based on the SeaWiFS lunar observations,the influence factors on lunar reflective property and the current models,ROLO and MT2009,are analyzed for improving the current models.
