Research on two Typical Estimation Algorithms of Doppler Frequency

摘要：

　　The accuracy of Doppler mean frequence estimation is vital in some related areas.In this paper,two typical estimation algorithms for mean frequency in time domain are discussed.Based on the mathematics derivation of different methods,the conclusion could be obatained that the precision was mostly influced by the amount of the sampling,signal-to-noise ratio (SNR),and the frequency of sampling.Then they were detailed analyzed and simulated in computer.The results of the simulations primarily indicate that the performance of complex-correlation algorithm is more advantageous than cross zero point algorithm in the same configeure condition.However,the complexity of its process is increased largely.
