摘　　要：本文基于多普勒效应的逆V模型来测量流速,该模型能够发射频率变化的扫频信号,回波信号经过谐振电路获取发射前后信号频率的变化。分析发射信号的逆V模型,设计核心回波电路,通过引入谐振电路单元和自相关解调电路单元,得到高质量的回波信号,可进行A/D采样等后续信号处理。This paper presents an inverse V model based on the Doppler effect to measure the flow rate, the model is capable of transmitting frequency sweep signal witb frequency changes, the echo signal through the resonant circuit, obtains the change before and after the launch of the signal frequency. First introduces the inverse V model of emission signal, then designes the core circuit, through the introduction of the resonant circuit unit and autocorrelation demodulation circuit unit, finally gets the echo signal of high quality, it is available for A/D sampling and other subsequent signal processing.
