论文摘要
交通安全是汽车雷达系统旨在追求的最重要的价值。与移动通信系统不同，雷达系统的文献没有充分解决雷达间干扰和安全威胁，例如干扰和欺骗，这又威胁到交通安全。在这种情况下，我们引入了一种新型的频率调节连续波（FMCW）雷达方案（即蓝色FMCW），可减轻干扰和欺骗信号。蓝色FMCW随机跳动频率，以避免干扰和欺骗信号。我们的相位比对算法能够消除相位不连续性，同时结合了随机跳动的chir频道信号，从而不损害雷达的分辨率。仿真结果表明，蓝色FMCW可以在各种情况下有效地减轻干扰和欺骗信号，而无需支付其分辨率。
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.
