Query: BlueFMCW: Random Frequency Hopping Radar for Mitigation of Interference
  and Spoofing   Traffic safety is the foremost value that automotive radar systems aim to
pursue. Unlike in mobile communication systems, the literature for radar
systems did not adequately address inter-radar interference and security
threats such as jamming and spoofing, which in turn threatens the traffic
safety. In this context, we introduce a novel frequency-modulated
continuous-wave (FMCW) radar scheme (namely, BlueFMCW) that mitigates both
interference and spoofing signals. BlueFMCW randomly hops frequency to avoid
interference and spoofing signals. Our phase alignment algorithm is capable of
removing the phase discontinuity while combining the beat signals from the
randomly-hopped chirps, and thereby radar's resolution is not compromised. The
simulation results show that BlueFMCW can efficiently mitigate the interference
and spoofing signals in various scenarios without paying its resolution.
