| Abstract: | Seawater sound velocity is one of the main factors affecting the performance of marine detection instruments.The sound velocity profiler is the major instrument for detecting the sound velocity of seawater.Researchers can use the sound velocity profiler to obtain the sound velocity of seawater along a section of a certain area as a function of depth,thus providing an accurate sound velocity profile for marine sounding instruments.It is of great significance to develop the marine economy,national defense and military science.This paper introduces the basic method of measuring sound velocity and the sound velocity profile techniques.Then it briefly summarizes the sound velocity profiles commonly used at home and overseas.Besides,the detection technologies of the sound velocity profilers are also discussed.Finally,this paper provides an overview of overseas companies who use advanced"Time of Flight"(TOF)techniques to measure sound speed. |
