Abstract

This paper carries out a research to analyze system transient response and its effect on sound speed measurement based on two frequency continuous wave (TFCW). Because the bandwidth of an actual measurement system is limited, the received signal is generally polluted by a system transient response, and it can significantly degrade the measurement accuracy of sound speed. We consider the actual system as a bandpass system. The phenomenon of transient response can be clearly noted, and simulations show that its effect on sound speed measurement is related to the starting time, the observation length of signal and the system bandwidth. To validate our research, we finally designed an experimental system to perform a sound speed measurement, and the experimental results are consistent with the simulations.
