Abstract :
A technique is described which embodies a robust approach to enhancing spatial resolution of aerospace images based on images made with another sensor with a better spatial resolution. The technique does not require an exact knowledge of the sensor angular functions replacing it with the analysis of a local signals spatial structure. The extent of correction of a low resolution image depends on its correlation with high resolution images. The universality of the technique is demonstrated by its applications to data of microwave and optical sensors
