| Popis: | This paper conducted depth and systematic research on the influence of image motion on radiation quality. The exploration of the regular image radiation quality could be a great significance for improving the image quality. The source of abnormal image motion was analyzed in terms of platform motion and flutter, attitude control error, and image motion compensation error. The model of point spread function under abnormal image motion was established based on the analysis of superposition model between adjacent pixels and PSF variation model. The radiation information and MTF caused by PSF changes were analyzed. The experiment shows that the authenticity of the radiation information expressing the imaging target is weakened. The larger the abnormal image motion, the faster the MTF curve declines, indicates the overall image quality decreases, the spatial resolution decreases, and the sharpness decreases. |
