| 摘 要： | 采用沙漠场景法、稳定目标法和交叉定标法对CBERS02B星的CCD相机开展时间序列定标,分别得到CCD相机2007-2008年期间三种方法对应的定标系数,并同CBERS02B卫星官方提供的定标系数进行比对.结果表明,三种方法得到的定标系数其误差均小于10%,不同方法的结果具有较好的一致性.最后,分析总结各种时间序列定标...

| Abstract: | The sensor on satellite is usually attenuated because of the intense ultraviolet radiance and cold space environment at the top of atmosphere.Three methods had been used to calibrate the CBERS02B CCD Camera in time series,which were desert sense calibration method,pseudo-invariance target calibration method and cross-calibration method,and the CBERS02B CCD calibration coefficients of three methods during 2007-2008 had been calculated.The relative differences of three methods' calibration coefficients were l... |
