摘　　要：时频分析技术是一种十分有效的地震资料处理技术。阐述了短时傅立叶变换的概念及性质。介绍了短时傅立叶变换在地震数据处理中的效果。利用自编的Matlab程序对地震数据进行短时傅立叶变换,生成分频率数据体;然后用Surfer软件数据处理与显示功能来实现地震剖面的分频显示。The time- frequency analysis technique is a very effective technique in processing of seismic data. Expatiate the idea and property of the short-time Fourier transform. Introduce the effect of seismic data processing by short-time Fourier transform. Using self-programed Matlab program process seismic data to do time frequency analysis, create the frequency-divisional data; Then we use the data processing and display function of Surfer software realize the frequency-divisional display of seismic profile.
