比值法光学遥感器机上辐射定标的研究

Study of Ratioing Approach to Remote Sensor In-orbit Radiometric Calibration

本文在简要介绍光学遥感器各种机上辐射定标方法的基础上， 着重叙述了“太阳＋ 漫射白板＋ 比值辐射计”的机上定标方案。最后结合自行设计的比值辐射计及其测试结果对该系统的辐射定标精度进行了分析。

On the basis of introducing radiometric calibration approaches of remote sensor ,Solar-diffuse panel and ratioing radiometer approach to in-orbit radiometric calibration is discussed in detail.Finally, in reference to privately designed ratioing radiometer and its result of tests, calibration accuracy of this system is analysised.
