A Calibration Method for 77GHz Millimeter-Wave Radar Based on Virtual Instrument Technology
77GHz millimeter-wave (MMW) radar is mature in technology and widely used in intelligent vehicle environment perception, vehicle safety distance detection, etc. In order to evaluate and ensure its working performances in practical use, the target kinematics parameters of 77GHz MMW radar must be calibrated before installation. A simulated calibration method for target kinematics parameters of 77GHz 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 of the simulated calibration instrument are analyzed. A 77GHz 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, MMW radar resolution and accuracy of the simulated calibration instrument. The expand uncertainty of the simulated speed and range are 0.7km/h and 0.12m respectively, where k=2. The simulation and uncertainty evaluation results preliminarily verify the feasibility of the simulated calibration method and the performance of the simulated calibration instrument.
