TDI CCD相机系统响应非均匀性校正

Nonuniformity correction of system response based on the TDI CCD camera

本文分析了该TDI CCD相机系统响应非均匀性产生的原因,并在分析非均匀性校正算法的基础上,针对线阵TDI CCD遥感相机光电响应是线性的这一特点,采用两点定标校正算法,对每片TDI CCD进行了校正,得到了每一片TDI CCD的每一个像元的校正系数并给出了校正前后的统计特征。

In the paper, the nonuniformity correction of TDI CCD camera response is analyzed. On the basis of nonaniformity correction algorithm and linear characteristc of the photoelectric response of TDI CCD camera, every piece of TDI CCD is revised by two-point spatial nonuiformity correction.
