光学卫星测区有效成像覆盖周期预估方法研究

针对光学卫星成像时云导致的测区有效成像覆盖周期不确定问题,在卫星轨道计算的基础上,结合云量时空分布的历史统计规律、卫星历史观测数据的覆盖能力,研究建立光学卫星测区有效成像覆盖周期预估模型,回答测区有效成像覆盖效率与时间等问题,直接服务于光学卫星数据获取、产品生产和应用服务的计划安排和应用决策。

A Study on the Prediction Method of Effective Imagery Coverage Cycle in Surveying Area for Optical Satellites

Based on the calculation of the satellites orbits and passes , integrating with the spatio-temporal historical statistics of the seasonal cloud coverage and the historical data acquiring capability of the satellite , this research developed a prediction model of effec-tive imagery coverage of the mission area .The model proposed by this paper answered the questions related to effective imagery cover-age efficiency and its data acquiring time cycle , providing supports in the decision -making process regarding data acquisition , pro-duction and application , which conducted a solution to the uncertainty of the effective imagery coverage time cycle caused by the clouds especially in the large scale mission areas during the data acquiring of the optical satellites .
