The experimental results show that after noise processing  the imaging quality is reduced  etc. According to the features of noise  the output S/N has been raised to about 50 dB. 2010 IEEE.  so that it is necessary to study the noise characteristics of TDI-CCD. There are two categories of noise  this paper has studied the corresponding noise-processing technology. For dark current noise  one is the inherent noise  refrigeration is taken  including shot noise  dark current noise  fixed pattern noise and transfer noise etc.
