摘要/Abstract

摘要： 用泰勒级数展开的形式表示高动态的载波相位参数,给出了对高动态载体和各阶频率参数估计的四阶加权扩展卡尔漫滤波器(EKF),以及实现高动态跟踪滤波器必须的状态转移矩阵和动态噪声协方差矩阵.计算机模拟实验分析了对载波相位和各阶频率的跟踪结果.

关键词: 载波相位, 多普勒频率, 扩展卡尔曼滤波器

Abstract: With the carrer phase of received high dynamic signal calculated by a Tyler series, a weighed four dimensional extended Klman filter is given to track the carrier phase and varies steps of Doppler frequency.To practise the filter,its state transfer matrix and the dynamic noise covariance matrix is derived in detail.Finally the computer simulated tracking result and analysis is given.

Key words: carrier phase, Doppler frequency, extended Kalman filter
