| 摘 要： | 重点研究地理因子对卫星成像质量的影响,预估影响程度,为卫星规划调度提供辅助决策信息。本文分别分析光照、地形起伏、云层3个地理因子对可见光传感器成像质量的影响,给出考虑这些因素的可见光传感器辐射接收计算公式,并结合ArcGIS分析功能,建立了地理因子对可见光传感器成像质量影响预估模型。同时,考虑地形起伏对SAR成像的影响,给出了利用DEM数据求几何畸变系数的方法,利用ArcGIS建立地理因子对SAR成像质量影响预估模型。两个模型都给出了成像质量影响程度预估值计算方法,最后,本文基于ArcGIS软件实现其原型系统。

| Abstract: | Research on the affect of geography factors on the satellite imaging mainly focuses on pre-evaluating the influence to provide auxiliary decision-making information for satellite schedule.Taking illumination,cloud coverage and terrain into account,an influence pre-evaluation model of geography factors on visible light sensor imaging is presented to calculate the solar radiation received by spaceborne visible light sensor and considering the terrain feature.An influence pre-evaluation model of geography fact... |
