摘　　要：水冰是支撑国际月球科研站建设和运行所需的重要资源。红外遥感是探测月球水冰的重要手段,但却难以直接用于无阳光直射的永久阴影区。提出了一种基于光照散射强度模型的阴影区光谱信息校正方法,并构建了基于光谱吸收特征的水冰探测方法,实现了对于永久阴影区水冰信号的探测。应用该方法对月球南极沙克尔顿(Shackleton)和诺比利(Nobili)撞击坑进行分析,发现它们内部的永久阴影区存在水冰信号。该研究有望为国际月球研究站的选址和建设提供借鉴。Lunar water ice is an important target for the International Lunar Research Station(ILRS).Infrared remote sensing serves as a crucial tool for detecting lunar water ice,yet its direct application in the permanently shadowed region(PSR)poses challenges due to the absence of direct sunlight.In this study,we propose a spectral correction method for the PSR based on the sunlight scattering model.Additionally,we have developed a water ice detection methodology based on spectral absorption characteristics.The method was applied to two typical craters,Shackleton and Nobili,situated in the lunar south polar area,successfully unveiling water ice indications in both locations.The outcomes of our investigation are anticipated to offer valuable insights for the forthcoming site selection and establishment of the ILRS.
