We present an ultrashort range IEEE 802.11ad-based automotive joint radar-communications (JRC) framework, wherein we improve the radar's Doppler resilience by incorporating Prouhet–Thue–Morse sequences in the preamble. The proposed processing reveals detailed microfeatures of common automotive objects verified through extended scattering center models of animated pedestrian, bicycle, and car targets. Numerical experiments demonstrate 2.5% reduction in the probability of false alarm at low signal-to-noise-ratios and improvement in the peak-to-sidelobe level dynamic range up to Doppler velocities of $\pm 144$ km/h over conventional 802.11ad JRC.

基于多普勒弹性 802.11ad 的超短程汽车联合雷达通信系统

我们提出了一种基于超短程 IEEE 802.11ad 的汽车联合雷达通信 (JRC) 框架，其中我们通过在前导码中加入 Prouhet-Thue-Morse 序列来提高雷达的多普勒弹性。拟议的处理揭示了通过动画行人、自行车和汽车目标的扩展散射中心模型验证的常见汽车对象的详细微观特征。数值实验表明，与传统的 802.11ad 相比，在低信噪比下误报概率降低了 2.5%，并且在多普勒速度高达 $\pm 144 $ km/h 的情况下改善了峰旁瓣电平动态范围JRC。
