  • Accurate measurement of kinematic parameters of targets by environment-sensing sensors is the basic requirement for safe and efficient driving of intelligent connected vehicles. Among existing mainstream commercial vehicle-borne radar sensors, 24 GHz and 77 GHz millimetre-wave radars are different in speed, distance, and angle measurement performance because of their different working frequency bands and bandwidths. In order to evaluate the speed measurement performance of 24 GHz and 77 GHz millimetre-wave radars, we developed a simulated calibration facility for kinematic parameters of millimetre-wave radar targets based on the virtual instrument technique, and verifies The feasibility and the speed simulation accuracy of the simulated calibration facility were verified using simulated speed calibration results of 24 GHz and 77 GHz millimetre-wave radar samples. The results of the simulated calibrations and comparison of the uncertainty evaluations showed that the speed measurement repeatability and accuracy of the 77 GHz millimetre-wave radar sample are superior to that of the 24 GHz millimetre-wave radar sample.
