摘　　要：将希尔伯特黄变换应用于水声矢量信号处理之中,提出了矢量希尔伯特黄变换法(矢量HHT)。新方法先对水声矢量信号进行经验模态分解(EMD),再对各阶本征模态函数(IMF)信号作希尔伯特变换和矢量信号处理。经理论推导和仿真研究,矢量HHT不仅继承了矢量信号处理和希尔伯特黄变换二者原有的优点,而且比常规方法有着更高的处理增益。An application of Hilbert-Huang Transform in underwater acoustic vector signal processing was introduced and a new method of Vector Hilbert- Huang Transform （Vector HHT） was developed, The new method first decomposes acoustic vector signal by Empirical Mode Decomposition （EMD）. Then it processes each Intrinsic Mode Function （IMF） using Hilbert Transform and Vector Signal Processing. According to theoretical deduction and computer simulation, the Vector HHT heritance of advantages of Vector Signal Processing and HHT has higher gain than traditional methods.
