【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。更多还原

【Abstract】 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.更多还原
