Abstract

As a new low noise CCD signal processing technology, digital correlation double sampling noise reduction technology is widely used in the field of faint astronomical target detection. In this paper, various noise sources of CCD video processing circuit are studied, the characteristics of various noises are analyzed deeply, the mathematical model of CCD circuit noise is established, and a noise reduction method based on digital correlation double sampling technology is proposed. Through simulation modeling of CCD noise signal, the simulation results show that the digital correlation double sampling method using double Gaussian filter function has a good effect on noise suppression.
