摘要：
Time-frequency distribution (TFD) of signals gains increasing applications in various areas of sciences and engineering for processing non-stationary signals and nonlinear signals. This paper presents our work of TF analysis of encountered wave signal in ship science using the Hilbert-Huang transform (HHT). The results in this paper exhibit that the HET based TFD of encountered wave signal has better resolution in comparison with those resulted from the traditional methods, such as short-time Fourier transform (STFT), wavelet transform (WT) TFD, and Choi-Williams TFD.
