It’s A Bird, It’s A Plane, It’s “That” UAV
Abstract: Unmanned aerial vehicles (UAVs) are being increasingly used for a number of sensitive applications, including surveillance, structural monitoring, communication relays, among others. Thus, identifying a specific UAV in a given swarm, in a manner that cannot be spoofed by software methods, becomes important. We propose RF fingerprinting for this purpose, where a neural network learns subtle imperfections present in the transmitted waveform. For UAVs, the constant hovering motion highlights a fundamental problem that impacts many previous works on RF fingerprinting: Since the wireless channel changes constantly, the network trained with a previously collected dataset performs poorly on the test data. This talk will cover some of our experiences, published solutions and open challenges concerning UAV detection using RF fingerprints. We will demonstrate outcomes on experimentally obtained RF datasets from a number of commercially obtained UAV models. We will conclude by identifying the high priority steps that the research community must focus on for robust and secure UAV fingerprinting, to make this paradigm suitable for real-world deployment.
