Utilizarea metodelor de localizare a unei surse radio în sisteme de detecție, localizare și combatere a dronelor / The use of radio source localization methods in drone detection, localization, and countermeasure systems

In this doctoral thesis, I highlighted variations in the usage of the main methods for radio source localization in drone detection, localization, and countermeasure systems. Additionally, based on the conducted research, I determined the most suitable methods and systems for designing a counter-drone system against unauthorized drone usage. This research is justified by the increasing unauthorized use of drones, which inevitably led to the emergence of threats and potential security vulnerabilities arising from the deployment of these technologies. Therefore, to protect strategic targets and national security interests, it is imperative to approach research in this field using appropriate means and methods. In this regard, in this thesis, I have implemented, together with members from the DRONEND project, a ground-based and an aerial system that incorporate subsystems for detection, identification, localization, and countermeasures using SDR (Software-Defined Radio) technologies. It should be emphasized that the completion of this project started from the current stage of research in this field and aimed at enhancing and optimizing existing solutions to achieve increased efficiency that meets current and future security requirements. In the research activity related to radio signal source localization algorithms and the use of SDR equipment - USRP for signal detection and processing, and ultimately for the development and validation of counter-drone systems against hostile intentions, I have successfully achieved the objectives outlined at the beginning of the work.
