| 摘 要： | 提高卫星遥感数据的质量，进而实现定量化应用，其基本前提和关键在于传感器的绝对辐射定标．为检验Terra卫星MODIS（Moderate-Resolution Imaging Spectroradiometer）传感器的星上定标系数的准确性和可靠性，2007．05在北京遥感综合实验场网内蒙二连浩特实验场，采用反射率基辐射定标方法对MODIS可见．近红外波段开展定标与真实性检验．结果表明，场地定标系数和MODIS的星上系数非常吻合，相对差异小于6％，证明场地反射率基辐射定标方法定标和MODIS星上定标得到的定标系数均准确、可信度高．

| Abstract: | Radiometric calibration is the key to improving quality and quantitative applications of the re- mote sensor data. A comprehensive calibration and validation experiment of M ODIS（ Moderate-Resolu- tion Imaging Spectroradiometer）visible and near-infrared bands was performed by National Spaceborne Demonstration at the ErLianhot test site in May 2007 in order to validate the veracity of MODIS onorbit calibration coefficients. The reflectance-based calibration method was used. It was found that the vicarious calibration results were in good agreement with the MODIS on-board calibration results with the deviation less than 6% at the ErLianhot test site. The results showed that the calibration results of both vicarious calibration and on-orbit calibration was highly reliable. |
