Study on the Preprocessing Techniques of Multi-temporal ERS-2 SAR Images Being Used in Crops Classification
多时相ERS-2 SAR图像在作物分类中的预处理方法研究

With its all\|weather,all time capability,radar remote sensing has great potential for agricultural application.A case on multi\|temporal ERS\|2 SAR images using in crops classfication was presented.Image temporal selection was based on backscattering characteristics and rotation practices of the major crops in the study area.Study on a series of preprocessing techniques on multi\|temporal ERS\|2 SAR Images,including calibration,geometrical correction and speckle reduction was introduced before they could be used later with accuracy.
