A Method of Seawater Sound Velocity Measurement Based on the Transit-Time

Abstract:

In the prospects of maritime development, the accuracy requirements of the marine sonar equipment also getting higher and higher, it is particularly important to measure the sound velocity in seawaters(ultrasound propagation velocity in seawater) in high-precision, in this experiment, basing on the seawater sound velocity variation influencing factors, proposing a method of average measuring the sound velocity of seawater based on STM32 and TDC-GP21 transit-time, The results of the experiment show that this method can be high-precision measurement of the size of the seawater sonic，meet the seawater sound velocity measurement requirements.
