In this book, the authors provide an inclusive and expansive vision of how radar will serve our increasingly efficiency- and security-conscious world. They do this by employing the model of holographic and ubiquitous radar (HUR) in which staring arrays are used such that the whole of a surveillance volume is continuously interrogated, with complex, ubiquitous signal data stored and analysed. This is essential reading for radar academics, military capability managers, senior industry engineers and engineering managers.
Increasing information content is an important scientific problem in modern observation systems development. Radar, or microwave, imaging can be used for this purpose. The book provides an overview of the field and explains why a unified approach based on wave field processing techniques, including holographic and tomographic approaches, is necessary in high resolution radar design. It contains discussion of new areas in imaging radar theory, holographic radar, the questions of estimation and improving radar image quality, and finally various practical applications.
This book provides a simple explanation of existing antenna arrays, their advances and limitations. It will lead you to nature-inspired next generation antenna array design and their advances. Why antenna arrays? Because antennas or antenna arrays are the primary element in any sensory system or circuit. Any artificial intellect, computer, vision, communication, or detection system cannot work properly without a properly designed sensor system or antenna array. They include not only technical areas like communication, navigation and radars, but also health care, medical imaging and even amateur metal detectors and RC vehicle design. Taking into account today’s military and geo-political threats, the book will also help you understand the functional needs of the new generation of antenna arrays for various radar and anti-missile systems to meet those threats. It also covers the evolution of antennas and antenna array design and gives insight into the fundamental function and advances of nature inspired new generation, fly eye antenna arrays and their applications. This book is intended for a wide area of readers and does not require special education, but it is a valuable resource for engineers and technicians who are involved in the design and development of all space communication and navigation systems, and drones, and hypersonic missiles detection systems, with special emphasis on interference immunity and protection. It also can be used as a textbook in advanced radar technology coursework and seminars.
Radar, Sonar, and Holography: An Introduction provides an introduction to the technology of radar and sonar. Because the new science of holography is affecting both these fields quite strongly, the book includes an explanation of the fundamental principles underlying this new art (including the subjects of wave coherence, interference, and diffraction) and of the hologram process itself. Finally, numerous examples are discussed which show how holography is providing new horizons to radar and sonar systems. The book thus also provides a simple approach to the new technology of holography. The discussions clarify the basic difference that exist between photography and holography, on the one hand, and between standard sonar and radar, on the other; and the hologram versions of these two technologies. The book should be useful as a supplementary reading assignment to early college students in science and engineering, and also to senior high students having a bent for science and engineering.
Covering a broad range of fundamental topics in classical optics and electro-magnetism, this book is ideal for graduate-level courses in optics, providing supplementary reading materials for teachers and students alike. Industrial scientists and engineers developing modern optical systems will also find it an invaluable resource. Now in color, this second edition contains 13 new chapters, covering optical pulse compression, the Hanbury Brown-Twiss experiment, the Sagnac effect, Doppler shift and stellar aberration, and optics of semiconductor diode lasers. The first half of the book deals primarily with the basic concepts of optics, while the second half describes how these concepts can be used in a variety of technological applications. Each chapter is concerned with a single topic, developing an understanding through the use of diagrams, examples, numerical simulations, and logical arguments. The mathematical content is kept to a minimum to provide the reader with insightful discussions of optical phenomena.
Clear, thorough account, without complicated mathematics, explains geometric and zone plate holography and the different types of holograms, along with step-by-step instructions for making holograms. 116 illustrations.
Holograms have been in the public eye for over a half-century, but their influences have deeper cultural roots. No other visual experience is quite like interacting with holograms; no other cultural product melds the technological sublime with magic and optimism in quite the same way. As holograms have evolved, they have left their audiences alternately fascinated, bemused, inspired or indifferent. From expressions of high science to countercultural art to consumer security, holograms have represented modernity, magic and materialism. Their most pervasive impact has been to galvanise hopeful technological dreams. Engineers, artists, hippies and hobbyists have played with, and dreamed about, holograms. This book explores how holograms found a place in distinct cultural settings. It is aimed at readers attracted to pop culture, visual studies and cultural history, scholars concerned with media history, fine art and material studies and, most of all, cross-disciplinary audiences intrigued about how this ubiquitous but still-mysterious visual medium grew up in our midst and became entangled in our culture. This book explores the technical attractions and cultural uses of the hologram, how they were shaped by what came before them, and how they have matured to shape our notional futures. Today, holograms are in our pockets (as identity documents) and in our minds (as gaming fantasies and 'faux hologram' performers). Why aren't they more often in front of our eyes?
The only all-inclusive treatment of holography—from fundamental principles to the most advanced concepts While several existing texts cover different aspects of the field of holography, none provides a complete, up-to-date, and accessible view of its popular, scientific, and engineering aspects. Now, from an author team that includes one of the world's pioneers in the field, Holographic Imaging fills this need with a single, comprehensive text that covers the subject from traditional holography to the cutting-edge development of the world's most advanced three-dimensional holographic images, holographic printing, and holographic video. Written in an engaging and easy-to-follow style, Holographic Imaging promotes a hands-on approach to making holograms and provides readers with a working understanding of how and why they work. Following a brief introduction to the fundamentals of light and diffraction, coverage includes: the diffraction efficiency of gratings, "platonic" holography, a ray-tracing analysis of holography, holographic lenses and in-line "Gabor" holography, off-axis "Leith & Upatnieks" holography, non-laser illumination of holograms, phase conjunction and real image projection, full-aperture transfer holography, white-light transmission "rainbow" holography, practical issues in rainbow holography, in-line "Denisyuk" reflection holography, off-axis reflection holography, edge-lit holography, computational display holography, holographic printing, and holographic television. Helpful diagrams and equations that summarize the mathematical and physical principles for each technique discussed make this an approachable resource for readers from a variety of backgrounds, including undergraduate and postgraduate students with an interest in optics, optoelectronics, and information display, as well as researchers, scientists, engineers, and technology-savvy artists.
