Abstract

Underwater sound propagation has many important applications of SONAR (Sound Navigation and Ranging) not only in military sector but also in civilization industry. The problem of 3D modeling of underwater sound propagation is coming from the need of calculation, estimation of sound pressure in order to support to SONAR applications. This paper propose a method of 3D modeling of underwater sound propagation using Normal mode (NM) theory and PDE (Partial Differential Equation) tool box of Matlab (There is currently no research paper using this approach). The parameters of Tonkin gulf were used in our simulations. With the water depth of 100 m, sea bed depth of 10 m and the transmission range of 2 km, the analysis and simulation results show the possibility of 3D visualization of the proposed method in Tonkin gulf as expected. The number of real mode are the same at all time but the mode fashions are different from time to time.
