| 摘 要： | 研究中巴资源卫星CBERS-02卫星数据大气校正的快速算法。首先假设地表为朗伯体，利用MODTRAN4．0软件模拟大气状况，讨论了不同地表反射率对大气校正参数的影响；然后计算出大气校正参数，生成查找表，根据CBERS卫星图像的不同情况确定不同的大气校正参数，从而对整幅图像进行大气校正。最后，利用核驱动模型对地表进行BRDF校正。 |

| Abstract: | In the paper,based on CBERS- 02 data,research for atmospheric correction was conducted.First,supposed land surface is a lambert,the influence of different surface reflectivity on the atmospheric correction was discussed by simulating the atmosphere with MODTRAN4.0;then,after building the LUT(look up table) which includes the coefficients of atmospheric correction,the whole data was corrected by the the proper coefficents in the LUT;at last,the land surface BRDF was corrected by Kernel-Driven Model. |
