摘　　要：遥感卫星辐射定标是提高遥感数据辐射质量、监测遥感卫星性能变化的重要途径。首先简要介绍了遥感卫星绝对辐射定标原理,讨论了现行遥感卫星绝对辐射定标方法及其优缺点,在此基础上提出了一种基于太阳定标基准星的在轨辐射定标方法,并对太阳定标基准星的轨道设计方法进行了研究。文章针对高分二号(GF-2)卫星的轨道特点设计了满足其遥感相机定标要求的太阳定标基准星轨道模型,据此分析GF-2卫星和太阳定标基准星的轨道关系,得到遥感相机对太阳定标基准星的可见时长,验证了此辐射定标方法的理论可行性,其计算和分析结果对提高今后我国遥感卫星辐射定标精度具有参考意义。The radiometric calibration of remote sensing satellite is an important way to improve radiometric quality of remote sensing data, and to monitor the radiometric performance of satellite. On the basis of introducing radiometric calibration of remote sensing satellite and discussing the advantage and disadvantage of currently absolute radiometric calibration methods to be used, a new on-orbit radiometric calibration method based on solar radiometric criterion satellite is presented. Then researches on orbit analysis and simulation is done to design a sun-based calibration criterion satellite orbit suited the calibration request of GF-2. According to the simulation above, the orbit relation of GF-2 and sun-based calibration criterion satellite is analyzed to get the access time between them. From the simulation the access time validates the theoretical possibility of radiometric calibration method proposed. The results can be meaningful in future for improving the radiometric calibration precision of domestic remote sensing satellite.
