摘要
从海地无线通信系统完成一个空中平台与多套船载设备之间高速数传的应用出发,针对空中设备对船载设备无线通信系统目标跟踪需求,设计了一种基于GPS定位数据的船载海面定向天线自动跟踪系统,阐述了自动跟踪系统的实现方案和跟踪算法。根据本地和目标位置信息,经过实时处理计算出目标相对本地的角度,利用伺服系统驱动定向接收天线,完成对目标的实时自动跟踪。工程验证表明,系统具有良好的跟踪效果。
According to target tracking requirements of land-sea wireless communications system,the thesis develops an automatic tracking device based on GPS for marine directional antenna,and describes its implementation and tracking algorithm. Based on local and target location information,the target angle relative to local location is calculated through real-time processing firstly,then the servo system is used to drive directional receiving antenna to realize automatic target tracking in real time.Engineering verification shows that the system has good tracking performance.
