从全球变化的空间观测需求出发,设想了一个依靠载人月球基地的对地观测望远镜,通过模拟地球静止轨道,太阳轨道和月球轨道,利用逐点计算法,从空间、时间和角度三个方面分析月球对地观测的覆盖特点,同时与现有的静止轨道卫星和日地 L1点对地观测作比较。分析结果表明,月基对地观测具有良好的时空覆盖性能,尤其是角度覆盖度优点突出,有助于完善多角度遥感以及全球能量平衡观测系统。
從全毬變化的空間觀測需求齣髮,設想瞭一箇依靠載人月毬基地的對地觀測望遠鏡,通過模擬地毬靜止軌道,太暘軌道和月毬軌道,利用逐點計算法,從空間、時間和角度三箇方麵分析月毬對地觀測的覆蓋特點,同時與現有的靜止軌道衛星和日地 L1點對地觀測作比較。分析結果錶明,月基對地觀測具有良好的時空覆蓋性能,尤其是角度覆蓋度優點突齣,有助于完善多角度遙感以及全毬能量平衡觀測繫統。

Based on the observation requirement of global change study,the point-by-point method was used to calculate the coverage indicators on the basis of orbit simulation and spherical ground triangulation. Then,a comparison was made among three platforms in space:Geostationary satellite,the Moon and the Earth-Sun L1 point.The result has shown that,though the temporal-spatial coverage from the Moon is only a little larger than that from Geostationary orbit,the moon offers a much better angular coverage, which is of great significance to the multi-angle remote sensing and the observation system to detect the Earth's energy balance.
