相对辐射定标与相对辐射校正场

相对辐射校正是提高遥感卫星图像质量的一个极其重要的途径，辐射校正场定标是相对辐射定标的一个行之有效的方法。本文在介绍了CCD遥感卫星成像原理和过程的基础上，分析了相对辐射校正的原理，进而阐述了进行相对辐射校正的三种方法。同时，本文还特别针对在轨对地定标探讨了选择相对辐射校正场的方法，并介绍了几个条件优越的相对辐射校正场。

Relative Radiometric Calibration and Radiometric Calibration Site

Relative radiometric calibration is a very important way in improving the quality of picture getting from remote sensing satellite , and calibration by radiometric calibration sites is just an effective method in relative radiometric calibration. By introducing the principle and the process of CCD camera remote sensing satellite image forming, the paper analyzed the principle of relative radiometric calibration, and then described three methods of carrying out relative radiometric calibration. Meanwhile, aiming at On-Board Calibration, the paper also discussed the method of selecting radiometric calibration site, and introduced several radiometric calibration sites which were thought as excellent.
