本专利提出一种通过特殊信号处理消除多普勒噪声的方法。这种多普勒速度仪可以从大量粒子测速结果中消除噪声信号,也可从被测流体速度低的大尺寸粒子测速结果中消除误差,从而提高多普勒测速仪的测量精
This patent proposes a method of eliminating Doppler noise through special signal processing. The Doppler velocimeter removes noise from particle velocity measurements and eliminates errors from large particle velocities with low fluid velocities to improve Doppler velocimetry
