Time-frequency Analysis of Seismic Data via the Multitapered Synchrdsqueezing Transform

Summary Time-frequency representation (TFR) can provide local spectral information in seismic data processing. High-quality TFR is important for analyzing these time-varying signals to characterize geological structures. Due to the Heisenberg uncertainty principle, traditional time-frequency methods (e.g. short time Fourier transform and continuous wavelet transform) always lead to ambiguous TFR which has negative effect on characterization of seismic signal with high resolution. A novel time-frequency representation method called the multitapered synchrosqueezing transform (MSST) is proposed to distinguish the different time-frequency contents. We introduce this promising time-frequency representation method to seismic data processing and show its effectiveness.
