| 摘 要： | 应用1995年7月在法国La Crau辐射校正场进行的遥感实验获得的SPOT HRV数据，在DOS方法的基础上，合理分析假设暗体反射率值，并结合Lowtran-7、6S、Modtran-3大气辐射传输模型进行大气模拟，研究并发展基于遥感影像信息的快速、经济、有效的大气辐射校正和反射率反演方法。通过La Crau场的反射率反演值与实时测量反射率值相比较，分析评价了该研究方法的有效性。

| Abstract: | The image based atmospheric radiation correction and reflectance retrieval approach were developed using the SPOT HRY data from La Crau radiant calibration site in July 1995. The approach was based on DOS method to calculate the path radiance with the reasonable dark object reflectance choice. The atmospheric transmittances,the downwelling atmospheric irradiance and atmospheric attenuation were inferred from several atmospheric radiative transfer codes (Lowtran 7,Modtran 3,6S) with simulated atmosphere. At last the aprroach was evaluated by comparing surface reflectances measured from La Crau site with that derived from SPOT data. |
