摘　　要：ETC作为智能交通的一部分,有效解决收费站缴费导致的拥堵滞留问题,加强行车的方便。但是同时,ETC也会存在旁道和跟车干扰问题。在停车场ETC应用环境中,提出采用新一代相控阵定位天线,结合FPGA对射频信号进行处理,通过一种算法计算得到OBU所在车辆的坐标位置,从而达到对车辆进行定位的目的。同时对于不同场景的车道布局,或天线方位角度安装不精确的情况下,提出一种自动校准补偿天线方位角的方法,在软件上,对误差进行自动纠正优化,从而达到更好的定位效果。As a part of intelligent transportation,ETC effectively solves the problem of congestion and retention caused by toll collection,and strengthens the convenience of the driver.But at the same time,there will be bypass interference and impending interference.In the ETC application environment of the parking lot,uses the new generation phased array positioning antenna,combines with FPGA to process the RF signal.Then through an algorithm to get the coordinate location of the OBU in vehicle,so as to achieve vehicle location.At the same time,for different scenarios of lane layout or imprecise installation of antenna azimuth,proposes an automatic calibration method for antenna azimuth,which can automatically correct and optimize errors on the software,so as to achieve better positioning results.
