Acoustic velocity measurement in seawater based on phase difference of signal

In this paper, FFT theory is used for realizing the phase measurement of signals. A new approach of acoustic velocity measurement in seawater based on phase difference is proposed. To deal with the phase ambiguity, our current study found an improved approach, which is based on two-frequency signal....
