AbstractThe method of Spatial convolution is applied to analyze the imaging process of the CCD imaging system, which involves optical imaging process and CCD integral sampling process, and the ratio between GRD and GSD that is called Kell coefficient is introduced, based on which, analysis of effect of Kell coefficient on the quality of aerial photography is educed. Imaging process of the target is simulated with different Kell coefficient values by Matlab. The method of the gray difference between the target and the image on CCD which is regarded as the evaluation criteria is proposed to evaluate the image quality. The simulation results show that when Kell coefficient equals 2.8, the target characteristics can be distinguished.; The method of Spatial convolution is applied to analyze the imaging process of the CCD imaging system, which involves optical imaging process and CCD integral sampling process, and the ratio between GRD and GSD that is called Kell coefficient is introduced, based on which, analysis of effect of Kell coefficient on the quality of aerial photography is educed.
