This book introduces simultaneous source technology and helps those who practice it succeed. Although the book does not include all developments, which would have en­tailed a much longer treatise, this work is written through the lens of decades of experiences and allows readers to understand the development of independent simultaneous sourcing. The relationships between data acquisition and data processing are discussed because never before have they been so intertwined as in this area. In addition to describing the underlying technologies, this book also is a user-guide which discusses survey design and acquisition and decribes the sensitivities of the processing algorithms which can allow simultaneous source technology to succeed. The audience for this book includes acquisition and pro­cessing geophysicists who will work with these data as well as those who require only an overview of the state of the art; and, even though they may not need the full technical details, they may want to know the limitations and advantages of using simultaneous sources.

This volume is designed to give the practicing geophysicist an understanding of the principles of prestack migration, presented with intuitive reasoning that avoids difficult math. Modeling with common-shot record and a constant-offset section are used to introduce prestack migration. New material in this revised edition of the original 1998 book includes algorithms that lead to and include Claerbout's inversion method.

This volume is designed to give the practicing geophysicist an understanding of the principles of poststack migration, presented with intuitive reasoning rather than laborious math. Modeling is introduced as a natural process that starts with a geologic model and then builds seismic data. Migration is then described as the reverse process that uses seismic data to find the geologic model. Many other topics are covered relating to the quality of the migrated section, such as aliasing, rugged topography, or use of the correct velocity. Significant new material has been added in this revised edition of the original 1997 book, especially algorithms based on the phase-shift method, such as PSPI and the omegaX method.

This volume provides a broad and uniform introduction of PDE-constrained optimization as well as to document a number of interesting and challenging applications. Many science and engineering applications necessitate the solution of optimization problems constrained by physical laws that are described by systems of partial differential equations (PDEs)​. As a result, PDE-constrained optimization problems arise in a variety of disciplines including geophysics, earth and climate science, material science, chemical and mechanical engineering, medical imaging and physics. This volume is divided into two parts. The first part provides a comprehensive treatment of PDE-constrained optimization including discussions of problems constrained by PDEs with uncertain inputs and problems constrained by variational inequalities. Special emphasis is placed on algorithm development and numerical computation. In addition, a comprehensive treatment of inverse problems arising in the oil and gas industry is provided. The second part of this volume focuses on the application of PDE-constrained optimization, including problems in optimal control, optimal design, and inverse problems, among other topics.

The last research frontier in high frequency electronics now lies in the so-called THz (or submillimeter-wave) regime between the traditional microwave and infrared domains. Significant scientific and technical challenges within the terahertz (THz) frequency regime have recently motivated an array of new research activities. During the last few years, major research programs have emerged that are focused on advancing the state of the art in THz frequency electronic technology and on investigating novel applications of THz frequency sensing. This book serves as a detailed reference for the new THz frequency technological advances that are emerging across a wide spectrum of sensing and technology areas. Contents: THz Technology: An Overview (P H Siegel); Two-Terminal Active Devices for Terahertz Sources (G I Haddad et al.); Multiplier and Harmonic Generator Technologies for Terahertz Applications (R M Weikle II et al.); Submicron InP-Based HBTs for Ultra-High Frequency Amplifiers (M Urteaga et al.); THz Generation by Photomixing in Ultrafast Photoconductors (E R Brown); Silicon-Germanium Quantum-Cascade Lasers (R W Kelsall & R A Soref); Plasma Wave Electronics (M S Shur & V Ryzhii); T-Ray Sensing and Imaging (S P Mickan & X-C Zhang); Multistatic Reflection Imaging with Terahertz Pulses (T D Dorney et al.). Readership: Undergraduates, graduate students, academics and researchers in electrical & electronic engineering.

Most data from satellites are in image form, thus most books in the remote sensing field deal exclusively with image processing. However, signal processing can contribute significantly in extracting information from the remotely sensed waveforms or time series data.
