    Abstract:

    77 GHz millimeter-wave (MMW) radar technology is mature and widely used in intelligent vehicle environment perception, vehicle spacing measurement for driving safety, etc. In order to evaluate and ensure its working performances in practical use, the target kinematics parameters of 77 GHz MMW radar must be calibrated before being used. A simulated calibration method for the target kinematics parameters of 77 GHz MMW radar based on virtual instrument technology is proposed and a simulated calibration instrument based on virtual instrument is developed. The basic principle of the simulated calibration method and the main design ideas and technical parameters of the simulated calibration instrument are analyzed. A 77 GHz MMW radar sample is chosen for speed and range simulated calibration, and the uncertainty of the calibration results is analyzed and evaluated from the aspects of measurement repeatability, radar resolution and accuracy of the simulated calibration instrument. The expand uncertainty of the simulated speed and range are 0. 7 km/ h and 0. 12 m respectively (k = 2), which preliminarily verifies the feasibility of the simulated calibration method and the performance of the simulated calibration instrument.
