Abstract It's difficult to detect the starting point of signal during measuring time-of-flight of sound propagation, caused by which measurement error should be eliminate. A comprehensive measurement algorithm based on time-frequency analysis is proposed to obtain high-precision ultrasonic velocity. Firstly, cross-correlation method within time domain is used to measure the whole cycle time of sound wave traveled; then, phase difference in the signal frequency domain is used to obtain the ultrasonic propagation group delay information; finally, the high-precision time-of-flight measurement is obtained by combining time and frequency domain information, so as to improve the measurement accuracy of sound velocity. By building the sound velocity measurement platform employed “FPGA + microprocessor” architecture, results show that the algorithm is effective and instructive to practice.

Key words： metrology acoustic velocity measurement time-frequency measurement cross-correlation method time-of-flight starting point
