    Abstract
  • To improve the velocity accuracy and range resolution of Doppler flow measurement technology, this paper comprehensively compares the waveforms of the signals with large product of time-width and bandwidth between the Costas frequency-coded signal and several phrase-coded signals considering practical application condition. It is revealed that binary phase shift keying(BPSK) signal is more benefitial to achieving high velocity accuracy and range resolution, and gains better anti-reverberation ability at low speed. The accuracy of Doppler frequency is estimated in simulation by using the complex autocorrelation algorithm. The results show that BPSK signal can help to obtain the minimum variance of velocity characterization, and is more suitable for the measurement of high-resolution Doppler flow velocity.
