摘　　要：借助地面参照物,在引入GPS定位功能的基础上,提出了一种灵活、快速的车载雷达方位标定方法。由于其中的地心角计算公式复杂,给出了地心角的近似计算方法。结果表明,当GPS定位精度为2m,相对距离为800m的地方角度误差小于0.286°17.172′,此精度已经超过了低档陀螺电子寻北仪。An agile and fast vehicle-borne radar azimuth calibration method is presented by means of the reference substance and GPS location. The approximation calculation method is given for the previous algorithm＇ s complexity. The results show that the precision is better than the low-end gyroscope while the location precision is less than 2 meters and the relative distance is more than 800 meters which is less than 0. 286 degree and 17. 172 centigrade.
