应用Fourier变换法分离提取地震记录中不同模态的瑞雷面波，其原理是：利用瑞雷面波各模式传播速度的差异，将时间域中叠加在一起的瑞雷面波信号在频率波数域中分开，以此实现分离提取各阶模态瑞雷面波。研究结果表明：τ-p变换只能提取浅部能量较强的部分瑞雷面波，不能提取瑞雷面波的全部频散成分且不能使不同模态瑞雷面波分离；利用Fourier变换可以准确分离提取不同模态的瑞雷面波，且经分离后计算所得频散曲线的频带宽度扩展，有利于提高瑞雷面波勘探的能力。

Title: Fast Fourier Transform - Algorithms and Applications Author(s): K.R. Rao, D.N. Kim, J.-J. Hwang (auth.) Series: Signals and Communication Technology Publisher: Springer Netherlands Year: 2010 Edition: 1 Language: English Pages (biblio\tech): 426\437 ISBN: 1402066287, 9781402066283 Fast Fourier Transform - Algorithms and Applications presents an introduction to the principles of the fast Fourier transform (FFT). It covers FFTs, frequency domain filtering, and applications to video and audio signal processing. As fields like communications, speech and image processing, and related areas are rapidly developing, the FFT as one of the essential parts in digital signal processing has been widely used. Thus there is a pressing need from instructors and students for a book dealing with the latest FFT topics. Fast Fourier Transform - Algorithms and Applications provides a thorough and detailed explanation of important or up-to-date FFTs. It also has adopted modern approaches like MATLAB examples and projects for better understanding of diverse FFTs. Fast Fourier Transform - Algorithms and Applications is designed for senior undergraduate and graduate students, faculty, engineers, and scientists in the field, and self-learners to understand FFTs and directly apply them to their fields, efficiently. It is designed to be both a text and a reference. Thus examples, projects and problems all tied with MATLAB, are provided for grasping the concepts concretely. It also includes references to books and review papers and lists of applications, hardware/software, and useful websites. By including many figures, tables, bock diagrams and graphs, this book helps the reader understand the concepts of fast algorithms readily and intuitively. It provides new MATLAB functions and MATLAB source codes. The material in Fast Fourier Transform - Algorithms and Applications is presented without assuming any prior knowledge of FFT. This book is for any professional who wants to have a basic understanding of the latest developments in and applications of FFT. It provides a good reference for any engineer planning to work in this field, either in basic implementation or in research and development.
