A study on forecasting equation of sound velocity for seafloor sediments based on principle component analysis
基于主元分析技术的海底沉积物声速预报方程

In order to obtain a forecasting equation of sound velocity for seafloor sediments,the authors first apply the technology of principal component analysis and analyze existing empirical equation and its calculation errors.A principle component model is then built up using the measurement data of sediments from the continental slope and shelf in southern South China Sea.The authors also studied in theory how to exclude correlated parameters from a number of parameters that can affect the sound velocity and ho...
