28 GHz 5G-Based Phased-Arrays for UAV Detection and Automotive Traffic-Monitoring Radars

This paper presents a frequency modulated continuous wave (FMCW) long-distance and high-resolution radar system using 28 GHz phased-arrays designed for 5G communications. Measurements show that this radar system can provide detection range for a small UAV with a 0.15 m range resolution. It also shows that the phased-array can provide good angular tracking as well as range finding. This paper clearly demonstrates that 5G phased-arrays are capable of more than just communication and can be used for a multitude of functions.
