Hehet Phenomenon Of Ocean Front And T Effect For Sound Propagation

1） For the research into the effect on sound propagation,The article use forreference gauss theorem and hydrologic data of ocean front in south of Taiwanchannel owing to the kuroshio.It set up mathematic model and acoustical velocityexpression of the sea area for the first time. Draw a parallel between observationaldata, the ocean front model can simulate environmental condition well and truly. atthe same time，the article adopts the data of Argo to initialization，bases Krakenmodel of acoustics to numerical value simulate sound propagation of this area.The outcome make know the experiment is exact and effectual.For the capability of sonar，the environment is important，it can make theequipment exerts well，also can make it abatable. On account of ocean front，thetemperature of seawater changes acutely. Ocean front is important to the work ofsonar. The article is according as the characteristic of ocean front，making use of MMPEmodel of underwater sound field，investigating the characteristic of soundpropagation in ocean front，and discussing the effect to sound propagation with theintensity of ocean front、frequency and position of sound.
