Abstract: Traffic safety is the foremost value that automotive radar systems aim topursue. Unlike in mobile communication systems, the literature for radarsystems did not adequately address inter-radar interference and securitythreats such as jamming and spoofing, which in turn threatens the trafficsafety. In this context, we introduce a novel frequency-modulatedcontinuous-wave (FMCW) radar scheme (namely, BlueFMCW) that mitigates bothinterference and spoofing signals. BlueFMCW randomly hops frequency to avoidinterference and spoofing signals. Our phase alignment algorithm is capable ofremoving the phase discontinuity while combining the beat signals from therandomly-hopped chirps, and thereby radar s resolution is not compromised. Thesimulation results show that BlueFMCW can efficiently mitigate the interferenceand spoofing signals in various scenarios without paying its resolution.
