Written by one of the field's leading experts, this landmark reference presents a thorough system analysis of the fiber-optic gyroscope (FOG), describing the concepts that have emerged as the preferred solutions for obtaining a practical device.This book's first edition was published in the early 1990's. If the basic design rules of the FOG have remained unchanged, the technology has certainly matured, and the expectations presented in the first edition have been largely exceeded. This second edition is updated throughout, featuring new content on Allan variance; testing with optical coherence domain polarimetry; the Shupe effect; and rare-Earth doped fiber ASE sources. In addition, brand new comprehensive appendixes cover the optics, single-mode fiber optics, and integrated optics necessary to understand the fiber gyro and provide an appropriate vocabulary for communicating with electronic component designers.

Phased Array Antenna Handbook provides new material on array and multibeam antennas and systems, including new methods, devices and machine learning techniques.

Since the second edition of this book was published in 1996, planar transmission line technology has progressed considerably due to developments in ultrawideband (UWB) communications, imaging, and RFID applications. In addition, the simultaneous demands for compactness of wireless electronic devices while meeting improved performance requirements, necessitates increased use of computer-aided design, simulation, and analysis by microwave engineers. This book is written to help engineers successfully meet these challenges.Details include the development of governing equations, basis functions, Green's function and typical results. More than 1200 equations supplement the text. Special attention is given to the use of simulation software in the design of complex devices and understanding the connection between data collected from simulation software and the actual design process.The book is primarily intended for microwave design engineers and RD specialists who need to employ planar transmission lines in designing distributed circuits and antenna systems for a wide range of wireless applications. Advanced undergraduate and graduate students in electronics and telecommunication engineering will also welcome this addition to your library.

The book provides practitioners and researchers with a complete overview of the latest and most important non-invasive and non-destructive techniques for inspecting structures and bodies by using microwaves.

\"Big Data\" is on the covers ofScience, Nature, theEconomist, andWiredmagazines, on the front pages of theWall Street Journaland theNew York Times.But despite the media hyperbole, as Christine Borgman points out in this examination of data and scholarly research, having the right data is usually better than having more data; little data can be just as valuable as big data. In many cases, there are no data -- because relevant data don't exist, cannot be found, or are not available. Moreover, data sharing is difficult, incentives to do so are minimal, and data practices vary widely across disciplines.Borgman, an often-cited authority on scholarly communication, argues that data have no value or meaning in isolation; they exist within a knowledge infrastructure -- an ecology of people, practices, technologies, institutions, material objects, and relationships. After laying out the premises of her investigation -- six \"provocations\" meant to inspire discussion about the uses of data in scholarship -- Borgman offers case studies of data practices in the sciences, the social sciences, and the humanities, and then considers the implications of her findings for scholarly practice and research policy. To manage and exploit data over the long term, Borgman argues, requires massive investment in knowledge infrastructures; at stake is the future of scholarship.

This cutting-edge resource introduces the basic concepts of passive bistatic radar, such as bistatic geometry, bistatic radar equation and analysis of different illuminating signals. These techniques, although known for almost a century, have not been developed intensively for decades, mainly due to technical limitations, but today, the passive radar concept can be realized in practice, and is of great interest for military and civilian users. This book provides insight into understanding the potential and limitations of passive radar systems, as well as the differences between signal processing in active and passive radar. Each of the signal processing stages typically applied in passive radar is described, including digital beamforming, clutter removal, target detection, localization and tracking. These concepts are illustrated with both simulated and measured data along with examples of passive radar systems.Correlation processing, which is crucial for passive radar operation, is presented, as well as practical approaches for calculating the cross-ambiguity function. The problems of range and velocity-cell migration are also introduced. The book analyzes and compares different antenna array geometries to show readers the appropriate solution for a particular scenario of passive radar. Cartesian tracking is also presented, based on the extended Kalman filter. Parallel and sequential updating approaches are introduced and compared. These concepts are illustrated with both simulated and measured data along with examples of passive radar systems, making this book useful for both novice and advanced practitioners.

In an era where climate change dominates global discourse, Felix Leach and Nick Molden dive deep into the complexity of vehicle emissions in their groundbreaking new book. Building on the insights from Felix's previous work, Racing Toward Zero, this new release confronts the bewildering landscape of automotive pollution with a clear, rigorous approach: what one piece of information can best describe the environmental impact of cars? Our digital age bombards us with information, yet meaningful understanding often eludes us, particularly when it comes to climate issues like road vehicle emissions. As simple solutions to such a complex problem remain elusive, Leach and Molden advocate for a sophisticated, yet accessible perspective.They propose a radical simplification of how we consider the environmental impact of cars and explore the multifaceted impacts of various vehicle powertrains, pushing beyond CO2 emissions to address broader environmental and societal concerns. The authors introduce the Molden-Leach Conjecture, a bold, universal solution that evaluates vehicles through a holistic lens. This conjecture offers a comprehensive framework to assess and regulate environmental impact, aiming to simplify complex choices for consumers and policymakers alike.They propose a new paradigm for taxing vehicles as we move away from fossil gasoline and diesel, enabling policymakers to address pollution and underpin tax revenues simultaneously. In a world where climate action is critical yet convoluted, Leach and Molden's book promises clarity and actionable insight. It's not just about finding answers-it's about finding the right ones. Join the journey to demystify automotive emissions and drive meaningful change.\"As a former Secretary of State for the Environment and, later, Industry I welcome this contribution to the most important challenge of our time.\"
