摘要 目前在遥感和 GIS中 ,关于误差和不确定性研究的主要方法有两种 :概率统计和机理模拟。本文论述了二者的特点 ,详细讨论了影响合成孔径雷达成像的诸多因素 ,提出利用机理的方法分析 SAR系统成像误差。本方法是从合成孔径雷达成像机理的研究出发 ,利用控制论的观点来解释、分析影响合成孔径雷达成像的诸多误差因素并建立误差传播模型。这不仅对研制合成孔径雷达的设计具有指导意义 ,而且对遥感数据的质量控制也有重要意义。 Curents Two kinds of methods tave been daveloped in dealing with error and uncertainty in remote sensing and geographic information system one is statistics method The other is mechanism analysis method We discussed the characteristics of these methods respectively Ginen the shortcoming of statistics method, we proposed one method belonging to mechanism method to analysis error propagation in Synthetic Aperture Radar It is very important value to data quality control and inversion of remote sensing
