Self-driving cars constantly assess their environment to choose routes, comply with traffic regulations, and avoid hazards. To that aim, such vehicles are equipped with wireless communications transceivers as well as multiple sensors, including automotive radars. The fact that autonomous vehicles implement both radar and communications motivates designing these functionalities in a joint manner. Such dualfunction radar-communications (DFRC) designs are the focus of a large body of recent work. These approaches can lead to substantial gains in size, cost, power consumption, robustness, and performance, especially when both radar and communications operate in the same range, which is the case in vehicular applications.

自动驾驶汽车的联合雷达通信策略：结合两种关键的汽车技术

自动驾驶汽车不断评估环境以选择路线、遵守交通法规并避免危险。为此，此类车辆配备了无线通信收发器以及多个传感器，包括汽车雷达。自动驾驶汽车同时实施雷达和通信这一事实促使以联合方式设计这些功能。这种双功能雷达通信 (DFRC) 设计是近期大量工作的重点。这些方法可以显着提高尺寸、成本、功耗、稳健性和性能，尤其是当雷达和通信工作在同一范围内时，尤其是在车载应用中。
