联合时频分析技术在地震勘探中的应用
|
摘要
联合时频分析是地震信号处理的一种重要分析工具,方法很多,应用广泛。阐述了各种传统联合时频分析方法的优缺点,同时还介绍了一种相对较新的联合时频分析方法——S变换法,列举了一些联合时频分析的应用例子,并证明了此法在地震资料处理和解释中的重要作用。
Joint time-frequency analysis is an important tool in seismic signal processing. With various realizations, this method is widely used in seismic prospecting. This paper discussed its advantages and disadvantages, and introduced briefly S-transform, a new realization of the method. Some real examples were presented.
