Ometanje prebrisavanjem sa diskretnim podopsezima - napredna strategija za sprečavanje dronova korišćenih u zlonamerne svrhe

Abstract

Malicious drones jamming is a subject of numerous researches in the world. The implemented jamming strategy is different in various cases and each improvement in the analysis, modeling and realization contributes to the jamming procedures originality. In this paper, we have analyzed implementation performances of sweep jamming with discrete subbands. This advanced method allows decreasing the problems caused by drone communication and/or telemetry signals jamming on the undesired disruption of navigation signals (GPS and GLONASS) used for the localization of friendly devices in the drone vicinity. The problem is analyzed on the example of one signal frequency intended for drone communication with its operator. Drones with this specific signal frequency are used relatively rarely, but the obtained results are the most illustrative for practical consideration of the problem. The specificity of this frequency is that it is nearest to the navigation signal frequencies which means that important conclusions made for this frequency are satisfied significantly easier for other frequencies intended for drone communication, video and telemetry signals transmission.
