【摘要】 常用天线自动跟踪方法有程序跟踪法和步进跟踪法,结合两种方法各自的特点(程序跟踪法跟踪动作快,步进跟踪法可获取信号极值),提出一种天线自动跟踪方法。该方法集程序跟踪法动作快和步进跟踪法跟踪信号为极值的特点于一体,比步进跟踪法动作速度快,比程序跟踪法更能适应微调,使天线在汽车等移动载体上实现卫星自动跟踪。最后,通过仿真说明该方法的有效性。更多还原

【Abstract】 Two methods of auto-tracking,such as program tracking method and step tracking method are introduced in this paper. Combined with the advantages of two methods,a new way of antenna auto-tracking is introduced. This method overcomes action slow of step tracking and the lack of program tracking on fine tuning,then completes the antenna auto-tracking in the car or other mobile carrier. Finally,the simulation shows that the method is effective.更多还原
