Abstract(s)

As Unmanned Aerial Vehicles (UAVs) are increasingly used for both commercial and military purposes, there has been much concern about the misuse of these devices in some restricted and security-sensitive areas. This dissertation focuses on developing and evaluating interference mechanisms, known as jamming and signal spoofing techniques, with the ultimate goal of disrupting both communications and navigation systems. For this purpose, Software Defined Radio (SDR) technology was used to design a cost-effective, adaptable system capable of neutralizing drones by interrupting their control signals and geolocation services. Experimental tests were conducted to assess the effectiveness of these implementations on commercial drones. The results showed that radio frequency jamming effectively disrupts control and image transmission. Spoofing also successfully emits false GNSS signals and indirectly interferes with the drone’s behavior.
