环境卫星CCD传感器场地辐射定标与交叉定标的比较
The Comparison Between HJ Satellite's CCD Sensors Field Calibration and Cross Calibration
摘要
Abstract
A series of calibration coefficients for HJ(Huan Jing)satellite's CCD sensor was calculated by reflectance calibration method, using the measuring spectrum data and atmospheric data which were collected at the test site of Dun-Huang, in August,2009. At the same time,those calibration coefficients were also gained by cross calibration method, using the Landsat-5 TM data. Comparing those two groups of results and the former calibration coefficients promulgated by China Centre for Resources Satellite Data & Application, it shows the consistency between the coefficients from the cross calibration and DunHuang field calibration varies less than 10%. Compared to the pre-launch calibration;the post-launch calibration has changed about 3.4% -6.7% in different bands of HJ satellite's CCD sensors.关键词
