| Abstract: | In order to improve spatial resolution of image collection system by subpixel technology,it must to research not only the ability of subpixel technology and methods of rebuilding HR image,but also the international relation of subpixel technology and other capability of system.The international relation of images matching,optical point spread function,apparatus SNR and subpixel technology are analyzed,and the results show that the key of subpixel technology of system is to keep balance between the advantage of subpixel technology in spatial resolution and other capability of system under different working environments. |
