Real-World ADS-B signal recognition based on Radio Frequency Fingerprinting

To meet the future needs of increasingly crowded airspace, the International Civil Aviation Organization (ICAO) proposed to use the Automatic Dependent Surveillance-Broadcast (ADS-B) to provide navigation and surveillance technology to solve the problems of security and capacity in the airspace. But ADS-B does not offer any authentication and encryption. So it is vulnerable to attacks by various illegal devices. A novel radiofrequency fingerprint (RFF) recognition method of aircraft identity verification based on deep learning is proposed. The ADS-B signal captured by RTL-SDR is used for confirmation. The experimental results show that the fingerprint is called the Contour Stellar Images with a better recognition effect under different networks and different SNR.
