Advancements in signal interference systems for targeted disruption of Unmanned Aerial Systems: An integrated approach using SDR and Custom RF Circuitry

This paper presents a comprehensive study on signal interference techniques for neutralizing a DJI Mavic Air drone. The research involved both lab-controlled experiments and field tests conducted on campus. A Software Defined Radio (SDR) and a custom-designed RF circuit were employed to implement the interference system. The focus was on disrupting the drone's video transmission, telemetry communications channel, and Global Positioning System (GPS) signal. Mathematical models and signal parameters were utilized to evaluate the effectiveness of different jamming strategies. The results provide valuable insights into the interference methodology for the IEEE 802.11b/n/g Wi-Fi standard and GPS C/A L1 signal, which are commonly used in commercial drones.
