It has also important application in seismic data analysis, for example, seismic spectral decomposition, instantaneous attributes extraction, etc.
在地震勘探数据分析中也有重要的应用，如地震频谱分解，瞬时属性提取等。
Spectral decomposition technology makes the theoretical resolution of the common seismic data achieved.
谱分解技术使常规地震资料达到理论分辨率。
Seismic signal is a typical of non-stationary signal. Spectral decomposition in essence is a continuous time-frequency analysis of a seismic trace.
地震反射是典型的非平稳信号，地震谱分解实质上就是连续时频谱分析。
