ABSTRACT
ABSTRACT: The mechanism of MTF (Modulation Transfer Function) and SNR (Signal Noise Ration) degradation in the TDI CCD (Time-Delayed-Integration Charge Coupled Device) optical camera imaging process was studied in this paper. The authors discussed the descriptive means for the signal and simulation method of MTF and SNR degradation in every stage by using the mathematic models and the signal transmission process. The MTF and SNR simulation flow had been established. Meanwhile, the simulation test was conducted for TDI CCD camera of MTF and SNR by using this method.
