摘要

汽车自适应巡航控制(ACC)需要一个前视传感器来提供其他车辆和物体相对于主车辆行驶方向的位置数据。这包括对间隔很近的车辆的辨别和对单个车辆和物体位置的精确测量。这些角度识别和角度测量要求，以及所需的传感器视场(FOV)，驱动了汽车前视雷达(FLR)的天线要求和天线架构。研究了波束宽度、波束重叠和波束数等关键天线参数。然后讨论了备选天线结构及其对ACC的适用性。

Antenna requirements and architecture tradeoffs for an automotive forward looking radar

Automotive adaptive cruise control (ACC) requires a forward looking sensor to provide data on the location of other vehicles and objects relative to the direction of travel of the host vehicle. This involves discrimination of closely spaced vehicles and accurate measurement of the position of individual vehicles and objects. These angle discrimination and angle measurement requirements, together with the sensor field-of-view (FOV) needed, drive the antenna requirements and antenna architecture for an automotive forward looking radar (FLR). This paper develops the key antenna parameters of beamwidth, beam overlap and number of beams. Alternate antenna architectures and their suitability for ACC are then discussed.
