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%.
