Modelling of Waveform Deformation in Time-of-Flight Estimation With Application to the Ultrasonic Pulse-echo Method

• The authors address the problem of estimating the time-of-flight of ultrasonic pulse-echo signals. The shape of the received waveform is modelled by a linear combination of base signals. A method for obtaining these base signals is presented. The method presumes that the excitation signal is narrow-banded in the frequency domain.
