摘要

利用贡格尔实验场对CBERS02B卫星进行场地反射率基法辐射定标

获得CCD相机可见近红外波段的绝对辐射定标系数

利用敦煌实验场对定标系数进行了真实性检验。结果表明:此次定标结果和测量值非常吻合

定标系数可信度高。

Abstract

A comprehensive calibration and validation experiment of CBERS02B CCD was performed by the Center for National Spaceborne Demonstration at the Gongger site on October 12

2007 in order to support the quantitative application program of CBERS02B data and improve the quantitative application level of CBERS02B data.The reflectance-based method was used to obtain CCD calibration coefficients for the quantitative application program of CBERS02B CCD data.The validation of the calibration coefficients was carried out at Dunhuang test site to verify reliability of the coefficients.It was shown that the vicarious calibration results were in good agreement with the measurement values.It was concluded that the calibration coefficients was highly reliable.
