声学海流计多普勒信号的采集与处理

THE DOPPLER SINGNAL ACQUISITION AND PROCESSING OF AN ACOUSTIC CURRENT METER

本文对超声波多普勒信号的噪音作了初步分析,探讨了在背景噪音污染严重的情况下采集多普勒信号的方法,并经实践验证了多普勒信号的采集与处理方案。 .

This paper deals with the primary analysis of the noise which affects Doppler singnal measurements and acquisition method of Doppler singnal in the condition of a serious noise pollution background. The measurements have proved that the scheme of the Doppler singnal acquisition and process is correct.
