To ensure the accuracy of navigation and aiming of modern unmanned aerial vehicles and cont-rolled means of destruction in any weather conditions and time of day, in conditions of interference, the most promising is the joint use of sensors of various physical nature for the detection and identification of targets (objects to be defeated). In this case, combined correlation-extremal systems are used to solve the problems of navigation (guidance). For the operation of such systems, it is advisable to form universal reference images. The methods for integrating digital images of a different range of waves to create universal reference images used in combined correlation-extremal navigation systems are analyzed. To form a universal reference image it is necessary to solve the problem of obtaining a «combined» image on the basis of seve-ral initial images of the same section of the terrain in different wave ranges. In this case, the problem of integrating images for the subsequent synthesis of a universal reference image is conveniently reduced to the task of combining in one image the characteristics common to the optical and radar images — the original images. That is why there is proposed a method for integrating radar and grayscale optical images which allows to create digital grayscale image combining the main informative signs of images of both ranges. The use of this method leads to an increase of the brightness and contrast of common fragments of the original images, does not lead to the destruction of correlation links, therefore the resulting composite images can use to form universal reference images.
