摘要
声场仿真是研究舰船声场和海洋声环境的重要手段,而声传播特性仿真是建立声场环境的关键一环。应用简正波理论并结合波数积分法,建立了浅海低频声传播特性的仿真数学模型。数值计算与资料实验数据表明,该仿真模型能较好地预报浅海低频声传播损失,具有计算精度高、计算速度快等优点。
Acoustic field simulation is an important part in sea combat field simulation. It is a key step to establish an acoustic wave propagation model in an underwater acoustic field. Using the Normal Model Theory and Wavenumber Integration Method, a low frequency acoustic wave propagation model in shallow sea of multi-layered media is constituted. This simulation model can forecast low frequency acoustic transmission loss perfectly. It has the properties of high precision and fast calculation velocity.
