Acoustic Travel-time Estimation by Fast Correlation Combined with up-sampling

摘要：

The key for acoustic temperature field measurement is to measure acoustic travel-time accurately.Restricted by sample interval,the acoustic travel-time estimation accuracy by fast correlating of the transmitted and the received signals is not high enough.A new method based on fast correlation combined with up-sampling is proposed.Ideal anti-imaging filters are implemented in frequency domain.Simulation research in MATLAB shows that it has much higher estimation accuracy compared with the fast correlation method.The larger the up-sampling factor,the higher the accuracy will be.
