动中通卫星天线圆锥扫描算法研究与应用
Research and Application of Algorithm in Conical Scan of On-the-move Satellite Antenna
摘要
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.关键词
