摘要:
 在动中通卫星天线中,最重的就是随动,即在载体(比如船、车或者飞机)摇晃的过程中,保持卫星天线的指向始终对准同步通信卫星. 圆锥扫描就是在卫星天线搜索到卫星的信标信号之后,通过在较小的范围内转动天线,使得天线指向轨迹呈椭圆状,每转一圈,通过传感器(信标机)记录下在椭圆的上下左右四个点的信号强度,根据这四点的信号强度找到卫星信号最强的点(即卫星的正真位置),再驱动电机使得天线绕该点画椭圆,最终使得卫星位置置于椭圆的中心. 怎样通过上下左右四点的信号强度,准确、迅速地调整天线指向,使得椭圆的中心与卫星信号最强的点重合,这是圆锥扫描过程至关重要的一点. 文中通过数据采集、曲线拟合、实践分析等方法找到了一种调整椭圆中心的算法,实践证明,该算法有很好的实用性.
Abstract:
 In on-the-move satellite antenna,the most important is servo which means follow-up in the carrier ( such as ships,car or plane) in the process of shaking,keep the satellite antenna pointing always on synchronous communication satellite. Conical scan is such a method,after satellite antenna detected the satellite beacon signals,rotating antenna in small scale,which makes the antenna pointing track a oval. Each round,through the sensor ( beacon) to record the signal strength of four points of up and down,left and right direction in a ova,according to the signal intensity of four points,find the strongest point of antenna signal ( i. e. ,the real antenna position) ,then the motor makes the antenna painting oval around the point,eventually making the satellite position at the center of the ellipse. How to ad-just the antenna pointing accurately and quickly through the four signal intensity,which makes the center of the ellipse in the position of the strongest point of the satellite signal,this is what conical scanning process do. In this paper,propose an algorithm through collecting data,curve fitting and practice analysis to adjust the center of the ellipse. Practice has proved that the algorithm has a good practicability.
