摘要为了推广在线检定方法在机动车测速仪现场实车检定中的应用,研制了一套基于多目标三维跟踪雷达的移动式机动车在线测速标准装置。首先介绍了该套移动式在线测速标准装置的设计要求;其次分析了标准装置中的速度、距离和角度测量工作原理,描述了标准装置速度测量值的溯源方法,并对速度测量误差的不确定度进行了评定;最后进行了实验室全量程模拟校准试验及真实交通流量状况大样本现场比对试验。结果表明:标准装置的速度测量误差在10～100km/h测量范围内为±0.5km/h,在100～300km/h测量范围内为±0.5%,并且车道测量准确率可达到100%。

Abstract：To promote the application of the online verification method in the field verification of vehicle speed measuring devices, a mobile reference instrument for online measurement of road vehicle speed based on multi-target 3D tracking radar is developed. The design requirement of the mobile reference instrument is firstly introduced. Then the working principles of speed, distance and angle measurement used in the reference instrument are analyzed, and the traceability method of speed measurement and uncertainty evaluation of speed measurement error of the reference instrument are described. Finally, the full-range simulated calibration tests in the laboratory and the large samples field comparison tests in actual traffic are carried out. The results show that the speed measurement errors of the mobile reference instrument are within ±0.5km/h at the speed value in the range of 10～100km/h and ±0.5% at the speed value in the range of 100～300km/h, and the accuracy rate of lane measurement is 100%.
