Here we present results of the statistical study of the accuracy of the local optical positioning system for the industrial GPR OKO-2. The results of measurement are forming a statistical set. The statistical set should verify the accuracy LPS. The proposed LPS uses special tapes with a special periodic pattern as a reference object. The video camera records the image of the marker tapes, was located on a fast mechanical scanner. The scanner produced an accurate movement of the camera perpendicular to the tape. During the moving process, LPS measures the distance between the camera and tape and compared it with the scanner data.

Radio-wave image restoration techniques are now intensively being researched at the Radiophysics Faculty of Tomsk State University. Key methods of radio-wave image reconstruction are examined in this paper. We describe the mathematical basis of adapted methods in the single scattering approximation. These methods are used at the Department of Radiophysics in the developed safety systems. The technique of differential hyperboles and Stolt’s method, for instance, were adopted from acoustic seismology. Mainly, geotomographic systems use these methods for imaging objects under the surface. Safety systems have close task, they are to detect prohibited items under the passengers’ clothing and in the luggage at railway stations or airports. Radio-wave tomography methods can reconstruct images of prohibited objects in the same way as X-rays safety system, but without X-ray radiation, so without harm for a human biology tissue.
