摘要:
为研究77GHz毫米波雷达用于车辆前向防撞探测的可行性，设计了一种汽车前向防撞探测系统装置，并针对结构化道路乘用车前碰撞工况，应用系统装置雷达对动态目标（车）的方位角、距离和速度测定，构建了前防撞预警模型与方法，道路测试表明：所设计探测装置对静态目标距离探测误差为4.5%，同时探测两个动目标的速度最大误差为5%，显然，77GHz毫米波雷达应用于车辆防撞预警系统设计具有可行性和独特优势。
Abstract:
In order to study the feasibility of millimeter wave radar for vehicle forward collision avoidance detection, a forward collision avoidance device was designed based on 77 GHz millimeter wave radar. Aiming at the low frequency leakage wave signal and high frequency interference signal, the device used analog signal processing module and other hardware systems for preliminary filtering. On this basis, the distance and speed of the target were obtained through the processing of FIR digital filtering, FFT transform, constant false alarm detection and other digital algorithms. At the same time, a multi-stage pre-warning model and method was constructed based on millimeter wave radar azimuth detection principle and driving safety distance model for the forward collision condition of passenger cars on structured roads. Road test showed that the distance detection error of the device designed for static target was 4.5%, and the maximum error was 5% for detecting two dynamic targets at the same time. Therefore, it was feasible for 77 GHz millimeter wave radar to be used in the design of vehicle anti-collision warning system.
