Abstract:In this paper,part work of the plan 863-2 was summarized.The noise of CCD and the vedio signal of new TDI-CCD image sensor was analyzed,and different methods were applied to deal with different noises.Especially,that how to deal with the kTC noise and the resetting noise with the technology of CDS was introduced and was proved with the experiments.At last the S/N of the whole system was analyzed.
Keywords:Correlated double sampling  TDI  CCD  Noise  S/N
