Design of Servo Tracking System of Microwave Vehicle Antenna

根据GPS和电子罗盘技术,设计车载伺服跟踪系统。提出了车载微波天线的定向算法,得到了陆地移动状态下车载天线的俯仰角和方位角的计算方法。利用以PC为核心的上位机系统和以μP为核心的下位机系统的基于线程的抢先式多任务处理功能,解决了适时数据采集和适时控制,实现了车载微波天线伺服跟踪系统。

According to the techniques of GPS and electrical compass,in this paper a servo tracking system is designed,a directional algorithm of microwave vehicle antenna is presented and the way to calculate the angle of pitch and the angle of location under the moving state system on land is obtainedThe problem of real-time data collection and system control is solved and the servo tracking system of microwave vehicle antenna is realized by utilizing the line-based anticipated multitask managing function of the up state-machine system of PC core and the down state-machine system of μP core
