Study on The Acoustic Wave Flying Time Measurement Method Based on the Second Related Technology

摘要：

Accurate measurement of the acoustic wave flying time in furnace is the key of acoustic measurement technology of furnace temperature distribution. This paper proposes the acoustic wave flying time measurement method based on the second related technologies.First,the received signal is dealt with autocorrelation process,and then it is dealt by cross-correlation with reference signal,which realizes the reconstruction of useful signal in the noise signal.Finally,time-delay estimation is done based on the reconstruction signal. The simulation result shows that compared with generalized crosscorrelation method,this method shows stronger antinoise capability and higher measurement accuracy.
