摘要	To capture the space-borne remote sensing image with a high Signal-to-noise Ratio(SNR), this paper analyses the main factors effect on the SNR of images according to the chain of the CCD imaging system. The expression of SNR in the system was indicated in terms of the response model of CCD imaging system. By avoiding the independency of specific CCD model, a design method of overall-division-overall was proposed to implement the CCD imaging circuit with higher SNRs. A completion development method including a top-level design, a module-level design and a total-system test was described. The method was applied in design of the high-resolution CCD imaging circuit system of the Jilin-1 satellite. The radiation calibration experiments for the imaging system was performed and the idea image dada with higher SNRs were obtained. The experimental results indicate that the SNR of panchromatic image is 53.9 dB and that of multispectral image is 56.3 dB when their gray outputs are in the saturation of 80%. Moreover, the fused image shows a real color and magnificent. The proposed method provides references for design of other space-borne CCD imaging circuit systems in remote sensing fields. 2016, Science Press. All right reserved.
