Our country’s space-based science experiment satellite for debris monitoring was launched in July, 2013. The acquired image data was abnormal when this satellite flying across SAA (South Atlantic Abnormally) region. In this paper, image noise, especially live pixel noise and hot pixel noise in the image obtained by this satellite when flying across non-SAA region and SAA region, was statistically analyzed. Then influence on the CCD detection performance was evaluated. The results show that image noise generated in SAA region is 5 electrons more than non-SAA region. The SAA’s image noise includes plenty of live pixels and hot pixels, and for hot pixels’ longevity, it will generate long term influence on the CCD detection performance.
