【摘要】 在地震数据处理过程中,时频分析技术可以同时在时域和频域内观察信号的演变,提供信号的局部时频特征,因而广泛应用于各种不同的处理目的,如用于数据压缩、降噪、检测、能量补偿等,本文对不同的时频分析技术作了简要介绍,并对其优缺点、彼此间的相互关系进行了较为详细的论述。同时,对时频分析技术所面临的问题及发展方向谈了一点个人看法。更多还原

【Abstract】 In the process of seismic data enhancement,the technology of time-frequency analysis shows a good picture in the joint time-frequency domain and makes us know about the change of frequency along with the time clearly.So it can be applied into different kinds of process purpose,such as data compression、noise reduction、examination and energy compensation.This article has made the brief introduction to the different time-frequency analysis technology,and showed a more detailed discussion about their advantage and disadvantage and correlation.At the same time,I have brought forward some views about the question and the development direction which faced to the time frequency analysis technology.更多还原
