A Method To Improve The Accuracy Of Angle For Automotive Radar

摘要

By analyzing the data collected by automotive radar, it is found that the angular glint phenomenon which occurs during the movement of the target makes the angle measurement value fluctuate. In this paper, the mean value filtering method is used to smooth the angle measurement collected by the radar, the point number of the filtering algorithm limitted by the hysteresis effect caused by the mean filtering due to the vehicle's mobility is analyzed. By simulating and analyzing measured data, it's found that the method can reduce the angular glint error and improve the angular measurement accuracy of the radar.
