Abstract

The problem of improving the resolution of NOAA AVHRR images, which is no higher than 1 X 1 km²/pixel, is solved. The a priori information invoked for solution of this problem includes the assumption that the initial video data, first, have the higher (subpixel) resolution as compared to the AVHRR data. In addition, it is assumed that the recorded images are formed by a scanning spot with a fixed, but unknown, pupil function. A salient feature of the proposed approach is adaptive reconstruction of a 'spreading-smoothing' operator, which is, in its turn, the convolution of two point-spread functions (PSF), on describing the instrumental function of the scanner pupil and another simulating the interpolation method used for reconstruction of the missing values of radio brightness of the subpixel raster. Some examples of the improved resolution of real images are presented.
