Investigation of means of counteracting optical channels of information leakage using UAVs

Abstract

The article provides a brief overview of systems for detecting and countering unmanned aerial vehicles (UAVs), which can be used, among other things, to intercept information via an optical channel. Currently, small UAVs are widely used for unauthorized surveillance of important objects, carrying out terrorist attacks and sabotage, carrying prohibited goods, as well as in military affairs. In this regard, the task of countering UAVs, especially small UAVs, has been updated. The problem of countering UAVs, in particular, small UAVs, is multifaceted and has not yet been effectively resolved. An analysis of publications shows that there are quite a few analytical articles in this area, especially in the Russian-speaking segment. Most of the works are dominated by overly optimistic conclusions regarding the effectiveness of countering UAVs with existing means. Objective. Research and review of systems for countering and suppressing UAVs, as well as an assessment of the distance from which it is possible to recognize information of a different nature. Results. The article presents the results of the analysis of various systems for countering and suppressing unmanned aerial vehicles. Analysis of the sources made it possible to identify the basic principles of operation of UAV countermeasure systems. To date, the Russian segment of the market has quite effective countermeasure systems that allow combating UAVs without damaging the infrastructure of the protected facility. Also in the course of the research, theoretical calculations were made of the range of recognition of text and a person's face using a camera that can be installed on a mini-UAV.
