一种车载雷达的简易方向标定误差修正方法

针对车载雷达调平时，雷达调平误差和系统标定误差引起的雷达角度误差而影响车载雷达的定位精度，提出一种误差修正算法。通过设计的转角接口盒装置测出的雷达调平引起的角度误差，实现了车载雷达方位标定误差修正。试验结果表明，该车载雷达定位精度达到了国内同行业领先水平。

A Simple Method of Directional Calibration Error Correction for Vehicular Radar

In view of the fact that the radar angle error caused by radar leveling error and system calibration error affects the positioning accuracy of vehicular radar when the vehicular radar is leveling, an error correction algorithm is proposed. The angle error caused by radar leveling is measured by the designed corner interface box device, and the azimuth calibration error correction of vehicular radar is realized. The test results show that the positioning accuracy of the vehicle radar has reached the leading level in the same industry in China.
