Three Dimensional Variation of Underwater Acoustic Propagation due to Nonlinear Internal Wave / 非線性內波對水下音傳的三維擾動效應

碩士 / 國立臺灣大學 / 工程科學及海洋工程學研究所 / 99 / There is a biggest internal wave in the South China Sea. The amplitude can more than one hundred meter and the vertical current velocity can large then 2.5 meters per second. The internal wave perturbs the water column dramatically which affect sound propagation greatly. This thesis is about the sound propagation’s variation in three dimensions due to internal waves. The acoustic and environment data are from the 2007 NLIWI experiment. We study both depression and elevation internal waves simulates KdV formula analysis the 3D effect on acoustic propagation using FOR3D model.
