Background. Currently, a necessary condition for ensuring the safety of distributed natural and man-made objects is the monitoring of these objects in order to identify their pre-emergency conditions. Materials and methods. To control the state of objects, methods of non-contact optical control of the level of the vibration signal of the object were used with the help of IMMS, built into existing systems for remote sensing of the Earth. Results and conclusions. The state of the issue of vibration monitoring of distributed objects was analyzed. The practical absence of methodological restrictions on the frequency of the analyzed vibrations for IMMS analyzing images of test segments with vibrational blur is substantiated. The subpixel accuracy of the analyzers of the vibrational increment of the image area of a round mark is substantiated. A method for estimating the overall level of vibration intensity along complex trajectories is proposed, based on replacing the real vibration process with an equivalent rectilinear vibrational movement in the object plane, which provides an equal relative vibrational increment in the number of pixels that form an image of a round test segment with vibrational blur. A new disjunctive model for the formation of a trace of vibrational blurring of the image of a test segment of a round shape is proposed.
