The invention discloses a vehicle anti-collision warning method and device based on a millimeter wave phased array radar. The device is less influenced by environmental factors, high in distance measurement precision, good in reliability and capable of distinguishing multiple targets in a close range. The vehicle anti-collision warning method comprises the following steps: (10) obtaining environmental information: adopting an active millimeter wave phased array radar to obtain highway environmental information; (20) judging an environmental object: distinguishing a high-speed vehicle from a low-speed object according to the highway environmental information; (30) data analysis: respectively judging the speed, the distance and the orientation of the high-speed vehicle and the low-speed object; and (40) anti-collision warning: sending out anti-collision warning information when the distance is smaller than a safe distance; the vehicle anti-collision warning device comprises an environment information acquisition end (1) and a warning end (2), and the warning end (2) is connected with the environment information acquisition end (1) through wired or wireless data.

    本发明公开一种基于毫米波相控阵雷达的车辆防撞警示方法及装置,受环境因素影响较小、测距精度高、可靠性好、可近距离分辨多目标。本发明的车辆防撞警示方法,包括如下步骤:(10)环境信息获取:采用主动式毫米波相控阵雷达,获取高速公路环境信息;(20)环境物体判断:根据高速公路环境信息,将高速车辆与低速物体加以区分;(30)数据分析:分别对高速车辆和低速物体进行速度、距离、方位判定;(40)防撞警示:当距离小于安全距离时,发出防撞警示信息;本发明的车辆防撞警示装置,包括:环境信息获取端(1)和警示端(2),警示端(2)与环境信息获取端(1)通过有线或无线数据连接。
