摘　　要：针对散射通信车载站天线对准问题,开发了基于北斗双模终端的天线对准系统。该系统通过北斗定位定向获得通信车载站经纬度和车体方位,根据两端通信车载站的经纬度计算出通信方位角,输出天线控制信号驱动天线指向通信方向,实现了通信系统的天线一键对准。与现有的基于电子罗盘的散射天线对准系统进行对比分析,指出其存在对准速度慢、精度低的问题。试验与使用结果表明,该天线对准系统对准时间缩减到10 min以内,对准后可进行勤务话互通,操作更加便捷。According to the alignment system of antennas in troposcatter communication vehicular stations,an alignment system of antennas based on BD dual-mode terminals are developed.This system obtains the longitude and latitude of communication vehicular stations and vehicle azimuth by position and azimuth determination of BD.The azimuth angle can be calculated by using the longitudes and latitudes of the two sites of communication vehicular stations,and the control signals of antenna are output.The Antennas are drived to point to the communication direction.One-click alignment of antenna is realized.The alignment system of antennas in troposcatter communication based on electronic compass is analyzed.Compared with the existing troposcatter communication antenna alignment system,this system has such defects as slow alignment rate and low alignment accuracy of antenna.The experiment results show that the alignment time of new alignment system of antennas is reduced to less than ten minutes,the interworking of service telephone can be implemented after alignment of antenna,and the operation can be more convenient.
