Noise analyzing and processing of TDI-CCD image sensor
the noise in TDI-CCD image was analyzed and categorized according to the operating principle of TDI-CCD. TDI-CCD noise mainly comes from two ways
one is TDI-CCD proper noise
such as photo shot noise、non-uniformity noise、dark current noise、fix pattern noise、transfer noise and so on
the other is TDI-CCD noise interference in work process
such as reset noise and 1/
f
noise.Several noise processing methods were presented based on noise charateristics and the signal processing schemes of double-correlated sampling were given to eliminate KTC noise. As a result
