Ping Cai

Open publisher page 3 citations

Abstract

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.
