摘　　要：对Radarsat-2影像的成像特性、预处理方法进行了研究,并利用Radarsat-2影像和IRS-P6影像进行基于光谱特征变异法的土地利用动态遥感监测试验。通过实地调查、实测等方式对发现提取的变化图斑进行精度水平分析,评价了Radarsat-2卫星影像在重庆地区土地利用动态遥感监测工作中的应用潜力,为SAR卫星遥感数据在重庆地区的应用进行了有益的探索。This paper studied the image formation characteristics and the preprocessing methods of Radarsat-2 ima- ges, and conducted the dynamic remote sensing monitoring test of the land use based on the variation of spectral features through making use of the Radarsat-2 and IRS-P6 images. The changed speckles are found and extracted are analyzed at precision level through field survey and actual measurement, tec. This paper also evaluated the Radarsat-2 applying po- tential that Radarsat-2 images are used for dynamic remote sensing work of the land use in the area of Chongqing. It makes a useful exploration for the application of SAR remote sensing in the area of Chongqing.
