Review of Sound Propagation Modeling in Underwater Warfare Environment

Underwater sound propagation modeling is always one of the most important and popular problems in underwater warfare environment because sound is now the only medium which can propagate long range in the ocean.It is of important significance to the design and application of sonar and the surface or underwater deployment.The underwater sound propagation modeling theory is reviewed from seven main aspects and the application review of parallel algorithm in the underwater sound propagation modeling in the past decades is given.The developing trend of underwater sound propagation modeling has been put forward,which is 3D underwater sound propagation modeling and its parallel algorithm based on hardware equipment.
