Radar and Communication Spectrum Sharing addresses the growing conflict over use of the radio-frequency spectrum by different systems, such as civil and security applications of radar and consumer use for wireless communications. The increasing demand for this finite resource is driving innovation into new ways in which these diverse systems can cohabit the spectrum. The book provides a broad survey of recent and ongoing work on the topic of spectrum sharing, with an emphasis on identifying the technology gaps for practical realization and the regulatory and measurement compliance aspects of this problem space. The introductory section sets the scene, making the case for spectrum access and reviewing spectrum use, congestion, lessons learned, ways forward and research areas. The book then covers system engineering perspectives, the issues involved with addressing interference, and radar/communication co-design strategies. With contributions from an international panel of experts, this book is essential reading for researchers, engineers and advanced students in radar, communications, navigation, and electronic warfare whose work is impacted by spectrum engineering requirements.

This book presents a comprehensive set of radar and electronic warfare principles including many of the latest applications in a clear and consistent manner.

Radar array design aims at shaping a specific transmit/receive beampattern through optimizing array geometry, transmit waveform, and transmit/receive weight vectors. It is a hot topic among the scientific and industrial communities due to the advent of modern digital arrays with multiple digital transmit and receive channels, arbitrary digital waveform generators, and solid-state transmitters. The radar array beampattern is a critical performance metric, and there has been a proliferation of techniques for radar array design exploiting the mathematical results drawn from optimisation theory.

The ability to detect and locate targets by day or night, over wide areas, regardless of weather conditions has long made radar a key sensor in many military and civil applications. However, the ability to automatically and reliably distinguish different targets represents a difficult challenge. Radar Automatic Target Recognition (ATR) and Non-Cooperative Target Recognition (NCTR) captures material presented in the NATO SET-172 lecture series to provide an overview of the state-of-the-art and continuing challenges of radar target recognition.

Over the last ten years, the numbers of unmanned air vehicles (UAVs) or “drones” have changed from being just a few specialist systems, used for scientific data gathering and military purposes, to them proliferating in huge numbers. They are used across a broad range of different leisure, commercial and military activities. UAVs can be used for: movement of items in factories for manufacturing, passenger and freight transportation, can take various roles in the agriculture and forestry industries (dispensing seeds, watering and monitoring crops), remote sensing for the oil and gas industries, traffic flow monitoring, support of emergency services, hobbies, security, military and many other applications.

Radar cross section (RCS) is a comparison of two radar signal strengths. One is the strength of the radar beam sweeping over a target, the other is the strength of the reflected echo sensed by the receiver. This book shows how the RCS gauge can be predicted for theoretical objects and how it can be measured for real targets. Predicting RCS is not easy, even for simple objects like spheres or cylinders, but this book explains the two exact forms of theory so well that even a novice will understand enough to make close predictions. Weapons systems developers are keenly interested in reducing the RCS of their platforms. The two most practical ways to reduce RCS are shaping and absorption. This book explains both in great detail, especially in the design, evaluation, and selection of radar absorbers. There is also great detail on the design and employment of indoor and outdoor test ranges for scale models or for full-scale targets (such as aircraft). In essence, this book covers everything you need to know about RCS, from what it is, how to predict and measure, and how to test targets (indoors and out), and how to beat it.

This book presents a comprehensive tutorial exposition of radar detection using the methods and techniques of mathematical statistics. The material presented is as current and useful to today's engineers as when the book was first published by Prentice-Hall in 1968 and then republished by Artech House in 1980. The book is divided into six parts. Part I is introductory and describes the nature of the radar detection problem. Part II reviews the mathematical tools necessary for a study of detection theory. Part III contains tutorial expositions in a radar context of the classical signal-to-noise and a posteriori theories, both of which have played important roles in the evolution of modern radar. The unifying theme of the book is provided by statistical decision theory, introduced in the last chapter of Part III, which provides the framework for the chapters that follow. The first three chapters of Part IV contain a unified tutorial exposition of single and multiple hit detection theory. The last two chapters are respectively devoted to the use of the radar equation and a discussion of cumulative detection probability. The latter includes a procedure for minimizing the power-aperture product of a search radar. The performance of near-optimum multiple hit detection strategies are considered in Part V. These include binary and pulse train detection strategies. The first chapter in Part VI applies sequential detection theory to the radar detection problem. It includes the Marcus and Swerling test strategy and a two-step approximation to sequential detection. The second chapter contains the development of Bayes decision rules and Bayes receivers for optimizing the detection of multiple targets with unknown parameters, such as range, velocity, angle, etc.

To meet the need for a compendium of radar information essential for design and performance analysis, a book should combine elements of both a radar text and a handbook. Radar Essentials, 2nd Edition: A concise handbook for radar design and performance analysis delivers on this requirement: it contains the radar principles, data, and equations most useful for practicing radar engineers and also material to help those who are not radar experts understand and use the information. The book is comprehensive, and serves as a complete radar reference, yet compact enough to fit on an engineer's desk or travel with them.

When you need vital data fast, turn to Radar Essentials. This compact yet comprehensive reference has compiled the most used principles, data, tables, and equations that are used by radar and aerospace system designers on a daily basis. Experts and non-experts alike will find this to be their go-to source for recalling and understanding the fundamentals and employing them in design and performance analysis.

Through courses taught internally at the Institute for Defense Analysis, Dr. Roger Sullivan has devised a book that brings readers fully up to speed on the most essential quantitative aspects of general radar in order to introduce study of the most exciting and relevant applications to radar imaging and advanced concepts: Synthetic Aperture Radar (4 chapters), Space-time Adaptive Processing, moving target indication (MTI), bistatic radar, low probability of intercept (LPI) radar, weather radar, and ground-penetrating radar. Whether you are a radar novice or experienced professional, this is an essential reference that features the theory and practical application of formulas you use in radar design every day. With this book, you are taken step-by-step through the development of modern airborne microwave radar, up to the cutting edge of emergent technologies including new results on theoretical 2D and 3D SAR point-spread functions (PSF) and current discussions concerning dechirp/deskew processing, layover in SAR images, vibrating targets, foliage penetration, image quality parameters, and more. Plus, for students of electrical engineering, physics, and radar, this book provides the best source of basic airborne radar understanding, as well as a broad introduction to the field of radar imaging.

Increasing information content is an important scientific problem in modern observation systems development. Radar, or microwave, imaging, a technique which combines radar techniques with digital or optical information processing, can be used for this purpose. Drawing on their own research, the authors provide an overview of the field and explain why a unified approach based on wave field processing techniques, including holographic and tomographic approaches, is necessary in high resolution radar design. Such techniques use the complex field incident on an observation surface to produce a hologram, which can be used to reconstruct an image of the object or to restore some of its physical parameters. This makes it possible to extract the size, coordinates and radar cross-section of individual scattering centres.

Radar Interference Matters is rooted in 25 years of real-world radar interference experience. The author began work on a radar interference investigation in 2000, expecting it to last six months - yet aspects are still ongoing. Many interference and coexistence cases followed over the years, and these have shaped a wider understanding of spectrum coexistence, safeguarding, and interference management. Professionals often had to "feel their way through" these problems due to a lack of structured guidance. That gap in practical, experience-based knowledge provided the inspiration for the book.

The micro-Doppler effect appears as Doppler frequency modulations in coherent laser or microwave radar systems induced by mechanical vibrations or rotations of a target or any part on the target. These Doppler modulations become a distinctive signature of a target that incorporates vibrating or rotating structures, and provides evidence of the identity of the target with movement.

Radar Principles for the Non-specialist, 3rd Edition continues its popular tradition: to distil the very complex technology of radar into its fundamentals, tying them to the laws of nature on one end and to the most modern and complex systems on the other. It starts with electromagnetic propagation, describes a radar of the utmost simplicity, and derives the radar range equation from that simple radar. Once the radar range equation is available, the book attacks the meaning of each term in it, moving through antennas, detection and tracking, radar cross-sections, waveforms and signal processing, and systems applications. At the finish, the reader should be able to do an acceptable, first order radar design and to critique the design of others. Students, engineers, scientists and managers will benefit from this book. The more noticeable enhancements to the third edition are the additions of equation numbers, more numerical examples, tables and figures showing many of the concepts numerically, and exercises for almost all of the concepts. These enhancements make the book easier to learn from and easier to teach out of.

The first maritime surveillance radars in World War II quickly discovered that returns from the sea, soon to be known as sea clutter, were often the limiting factor when attempting to detect small targets while controlling false alarms. This remains true for modern radars, where the detection of small, slow moving targets on a rough sea surface remains one of the main drivers for maritime radar design, particularly in the development of detection processing.

Radar Techniques Using Array Antennas is a thorough introduction to the possibilities of radar technology based on electronic steerable and active array antennas.

This book presents a unique and comprehensive introduction to modern radar techniques using array antennas. The author focuses upon the principles, system concepts and techniques using electronic steerable and active array antennas for future high standard multifunction radar systems in both military and civil applications. Signal processing and array antennas are discussed from an engineering perspective, as a basis for system design. The key areas covered include array signal processing, adaptive digital beamforming, adaptive monopulse, superresolution, sequential detection, SAR with an active array for moving target detection, target imaging, adaptive clutter suppression, pulse compression with low range sidelobes and high range resolution, target detection with long pulse series, energy management and system parameter relations. Several new and effective radar techniques using array antennas are also discussed based on the pioneering work conducted by the authors team at FGAN, complete with experimental simulation results. The book will prove useful for engineers and scientists who work on research, development and systems design in the radar field as well as those who are responsible for radar decision making and planning within the government or industry.

This book provides an overview of radar waveform synthesis obtained as the result of computational optimization processes and covers the most challenging application fields. The book balances a practical point of view with a rigorous mathematical approach corroborated with a wealth of numerical study cases and some real experiments. Additionally, the book has a cross-disciplinary approach because it exploits cross-fertilization with the recent research and discoveries in optimization theory. The material of the book is organized into ten chapters, each one completed with a comprehensive list of references.

This is an enlarged and revised second edition of a book first published in 1978 and reprinted twice since then. The new edition includes updates to all the original chapters, plus two new chapters on developments in superresolution techniques and their application to direction-finding arrays.
