基于回归分析的动态校相实现方法

Dynamic phase calibration method based on regression analysis

为解决船载卫通站跟踪性能的检验与校准,分析了跟踪接收机校相原理,并扩展到动态环境下,利用跟踪陀螺信号中包含的天线运动信息,与接收机输出的误差电压比较,通过Matlab线性回归的方法计算出跟踪接收机相位差值以及增益,实现跟踪接收机校相结果的重新校准。提高了船载卫通伺服跟踪系统的稳定性。

In order to solve the verification and calibration of the tracking performance in the shipboard satellite communication station,this paper analyzes the principle of tracking receiver phase calibration and extends it to the dynamic environment.To achieve the tracking receiver phase re-calibration,we take advantage of the antenna motion information contained in the tracking gyro signal,compare it with the error voltage of the receiver output and calculate the phase difference value and gain of the tracking receiver using Matlab linear regression method,which improves the stability of shipboard satellite communication servo tracking system.
