摘　　要：文章在阐述中国CBERS_1卫星对绝对辐射校正需求的基础上 ,论述了CBERS_1卫星的辐射校正方法和技术流程 ,着重阐述星地同步观测前的技术准备、星地同步观测中测量参数的数据采集方法和数据处理分析。最后计算出CBERS_1卫星CCD相机的绝对辐射校正系数和误差分析 。Based on the description of the requirement of CBERS_1 on the absolute radiometric calibration, as the foundation we first introduce the calibration method and technical scheme for the absolute radiometric calibration of resources satellites. Then, we emphasize the technical preparation before the in_flight calibration and some important technical issues about data collection technique, data processing and analyses for the simultaneous ground_based measurements. Finally, we give the absolute radiometric calibration coefficients and error estimates for the in_flight calibration experiment of CCD Camera for CBERS_1 at Dunhuang Test Site from August to September 2000. This study gives a good demonstration of the absolute radiometric calibration to other resources satellites and some analogical remote sensing satellites.
