一种双阵元干涉仪相位差变化率提取方法

A method of extracting phase difference change rate for a dual-element interferometer

针对传统相位差变化率提取方法提取误差较大的问题,提出一种采用周期间预测解模糊的方式,利用周期间的信息计算提取相位差变化率,并对提取算法进行仿真验证,仿真结果证明了其有效性和稳定性。

Given that the error of the conventional methods of extracting phase difference change rate is relatively large,a method of adopting periodic prediction ambiguity resolution is proposed.The phase difference change rate is calculated and extracted with the information between cycles,and the extraction algorithm is simulated and verified.The method proves effective and stable.
