碩士 / 國立臺灣大學 / 工程科學及海洋工程學研究所 / 99 / In The continental shelf regions offshore northeastern Taiwan, underwater sound propagation is influenced by the sediment enormously, so doing the acoustic studies in this regions, sediment acoustic parameters (including velocity, density, attenuation coefficient versus depth) becomes particularly important. Sediment data is collected mainly in two ways, one is to obtain core samples, however it’s difficult and limited by the number of site-sample. The second way is the geo-acoustic inversion, which used data of chirp sonar system to inverse the geo-acoustic parameter by the spectrum ratio method. The purpose of this research is to establish the geo-acoustic parameter in large area database of the northeast of Taiwan and to improve the accuracy of simulation in underwater acoustic propegation.
