An Adaptive Four Dimensional Kalman Filter for Doppler Frequency Tracking
Xiao Wang · Beijing Youdian Xueyuan xuebao · 2001
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.
