| 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. |
| Keywords: | computer simulation maximum likelihood estimator Doppler frequency FFT processing |
