Abstract

According to the close relation between spatial resolution and radiant resolution and utilizing the experimental equation of MRTD, it is proved that there is a selectable optimum value of IFOV for particular spatial frequency or spatial frequency region which is interesting. The convolution process of line scanner is also analyzed, it is concluded that the spatial resolution can greatly exceed the limit of IFOV as long as the contrast is large enough, especially for linear or spot targets. Thus, the relative phenomena of the satellite image can be explained effectively. It is indicated that the spatial resolution can further be improved, if the processing of solving convolution operation is carried out in the digitized image processing.
