Abstract: The Doppler frequency of received signal is calculated by a Tyler series, the maximum likelihood estimation of varies steps of Doppler parameter is derived and analyzed by experiment; The computer simulate the estimator by FFT processing. The estimate root mean square error and loss lock probability to estimate the given simulated receiver trajectory is presented.

Key words: computer simulation, maximum likelihood estimator, Doppler frequency, FFT processing
