摘要
本文介绍了时-频联合分析的几种方法,其中似正交吉勃离散展式和自适应高斯基表达式是信号分析领域有重要意义的最新成果,为地震数据处理开辟了新的途径。文中还给出了时-频联合表示的地震记录处理实例。
Several algorithms of signal representation in joint time-frequency domain are introduced herein, in which the orthogonal-like Gabor discrete expansion and adaptive Gaussian basis representation are the newly significant developments in signal processing field. These algorithms are great advantageous to the earthquake record processing. Examples of the earthquake record processing are also presented in this paper.
