摘　　要：以HJ-1A/B卫星CCD数据为例,确定遥感卫星数据辐射校正和几何校正的方法,通过改变辐射/几何校正顺序,设计遥感数据预处理研究流程,从图像的统计特征和纹理特征两个方面,定量化的分析辐射/几何校正的先后顺序对处理结果的影响.实验从统计特征和纹理特征两个方面对结果进行了分析,发现校正顺序对结果的影响很小,该实验说明辐射/几何校正顺序的不同对预处理结果的影响很小,同时也可以为HJ-1A/B卫星遥感数据的处理流程提供参考.In this paper,we used HJ-1A/B satellite CCD data as fundamental datum and processed them.Firstly,integrating data characteristics,the authors determined methods of radiometric and geometric correction.Secondly,technology roadmap was designed by changing the radiation and geometric correction order.Finally,the results obtained by different orders of radiometric calibration and geometric correction were quantitative analyzed from two aspects of statistical characteristics and texture features of images.The experimental results showed that：In the statistical and texture indexes of results,most of them had little difference.The experimental results can prove a fact that different correction orders have a little influence on the pretreatment results.This fact can provide a reference for the preprocessing of HJ-1A/B satellite CCD data.
