Seismic waves are non-stationary due to its propagation through the earth. Time-frequency transforms are suitable tools for analyzing non-stationary seismic signals. Spectral decomposition can reveal the non-stationary characteristics which cannot be easily observed in the time or frequency representation alone. Various types of spectral decomposition methods have been introduced by some resear...

seismic attribute is a quantitative measure of an interested seismic characteristic. there are several seismic attributes. in recent years, time-frequency (tf) attributes have been developed which to reach them, tf analyzing of seismic data is required. a high resolution tf representation (tfr) can yield more accurate tf attributes. there are several tfr methods including short-time fourier tra...

This paper provides a general overview of Time-Frequency reassignment and synchrosqueezing techniques applied to multicomponent signals, covering the theoretical background and applications. We explain how synchrosqueezing can be viewed as a special case of reassignment enabling mode reconstruction and place emphasis on the interest of using such time-frequency distributions throughout with ill...

Turbocharger is one of the vital parts a diesel engine causing high failure rate. Its surface vibration signal contains important time-varying features. To better process nonstationary signals with features and perform time-frequency transformation on turbocharger signal, novel multi-objective matched synchrosqueezing chirplet transform method proposed in this paper. The based Linear Chirplet T...

This paper provides a general overview of Time-Frequency reassignment and synchrosqueezing techniques applied to multicomponent signals in terms of the theoretical background and applications. Our goal is first to show how synchrosqueezing can be viewed as a special case of reassignment with the advantage of enabling mode reconstruction, under the assumption of small frequency modulation for th...
