Item Design of UAV detection system utilizing communication monitoring(University of Zilina, 2021) Brodniansky, Martin; Novák, AndrejAim of the paper is to design a system capable of detecting unmanned aerial vehicles utilizing radio communication sensing. The need to detect UAVs is caused by combination of their compact size, sensing capabilities, autonomous nature, ways of misusing them or their spread among unprofessional users unaware of their own risky handling of UAV. All these factors can lead to serious security threats and risk to human lives or infrastructure. In this paper, radio communication detection system is proposed as part of a robust system where radio detection is supplemented by other methods, to maximise probability of UAV detection. Significant attention was dedicated to deeper analysis of current progress in the area of radio communication detection systems as well as acoustic, visual and radar detection. Based on this analysis, all systems were compared together based on probability of detection and distances of detection. Comparation together with different properties of detection methods were basic stepping stone for final system proposal. Robust detection system was successfully designed with radio detection as its primary component, radar detection serving primarily as localizer of UAV, acoustic system serving as backup for detection of UAVs without radio communication and visual system for final confirmation of UAV, its model and presence of camera or loadItem Using SDR receivers for UAV detection(University of Zilina, 2021) Dianovský, Robert; Novák, AndrejAs the number of unmanned aerial vehicles (UAV) increases, new dangers arise for airports and other facilities. Because of this, the need for UAV detection and monitoring in areas, that might be endangered by their operation, is becoming an important topic. Introductory chapters are dedicated to the identification of potential risks posed by UAV operations and research of existing monitoring methods. The main goal of the paper, about which is this article, is to research the possibility of UAV detection by using accessible amateur SDR (Software-Defined Radio) for intercepting radio communications between UAV and its control station. Possible radio detection and localization methods were proposed based on the analysis of radio transmissions used in unmanned aerial systems. A simple theoretical design of SDR-based detection and localization system for monitoring unauthorized UAVs was developed by choosing appropriate methods. The principles and methods used in the design were experimentally demonstrated in several laboratory experiments. Successful realization of this design would possibly improve the availability of drone monitoring systems and reduce their production costs.
