Radar Interference Matters

Fri, 06 Mar 2026 17:36:30 GMT

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.

Each chapter has been inspired by real interference, coexistence and spectrum planning cases spanning air traffic control, air defence, space defence, vessel tracking service and meteorological radars. One chapter is dedicated to the problems of wind turbine interference to radar, and features updates on the author's previous book on the topic. The book includes a bibliography, and a chapter identifying future work in spectrum engineering, including AI applications and evolving regulatory needs.

The book is aimed at radar and spectrum engineers who are addressing radar interference matters, as well as researchers and students learning about radar interference.

GNSS-Enabled Autonomous Navigation

Wed, 11 Feb 2026 15:21:20 GMT

The world is moving into an era of unprecedented transformation driven by automation and intelligent systems. This future hinges not just on artificial intelligence and machine learning's intelligence but also - fundamentally - on autonomous systems' ability to know where they are and how they are moving with precision, dependably, and continuously. Navigation is the centre of all autonomous platforms. Navigation is that foundational ability whereby a system can be aware of where it is, where it must go, and how to get there safely. Global Navigation Satellite Systems (GNSS) not only enable navigation but also synchronization of telecommunications networks, electricity distribution and financial transactions, and constitute a central infrastructure of the digital age.

GNSS-Enabled Autonomous Navigation: Principles, technologies and challenges begins with an exposition of GNSS fundamentals, including satellite positioning concepts, signal structures, error sources, and system quality indicators - accuracy, integrity, continuity, and availability. It then presents an introduction to the augmentation and improvement methods that enhance GNSS capabilities to meet requirements for autonomous applications. The unifying theme of this book is the application of GNSS in the development of autonomous systems in various spheres. Chapters cover the role of GNSS in the development of autonomous ground vehicles, improving maritime navigation, aviation systems, robotics, and agricultural technology.

By bringing together theory and vision for the future, the book is aiming to provide researchers, engineers, and students with a comprehensive understanding of how GNSS is the key to autonomous navigation system development. The book brings to fore that the path towards full autonomy will be based on the complete convergence of navigation, communication, and intelligent decision-making technologies.

Model-Based Parameter Estimation in Computational Electromagnetics

Mon, 13 Oct 2025 08:07:04 GMT

Computational electromagnetics (CEM) involves modeling the interaction of electromagnetic fields with physical objects and their environment, such as the radiation emitted by antennas and the fields scattered from radar targets.

First-principles or generating models (GMs) based on Maxwell's equations, provide a microscopic, spatial description of the charge and current distributions that normally require several samples per wavelength. Model-based parameter estimation (MBPE) uses a macroscopic, reduced-order, physically based fitting model (FM) to adaptively sample GM results while minimizing the number needed to quantify various EM observables such as frequency responses, far-field radiation patterns, interaction effects, etc. The FMs can reduce the needed GM sampling cost by a factor of 10 or more while yielding a continuous result of needed observables to avoid missing important details. The FMs can also indicate the numerical uncertainty of such quantities from measured as well as computed data.

After an introduction to the subject and its mathematical background, subsequent chapters cover system identification, MBPE techniques and the various roles of Prony's methods as FMs in CEM. Other related topics that are covered include derivative sampling, radiation pattern synthesis and estimation, and assorted other applications.

The book is aimed at the computational electromagnetics community and those working in applied sciences with complex models such as acoustics, mechanical structures, geo-physics and physics.

Maritime Autonomous Vehicles

Fri, 12 Sep 2025 14:43:26 GMT

The maritime domain is of an enormous interest to our society, from the economy to health, and security. Operating in the maritime domain, on the other hand, is dangerous, expensive, and most of the time at low execution speed. Unmanned systems are in many ways suited to such environments, but the successful realisation of maritime autonomous vehicles requires an overarching design and development cycle, starting from design and modelling of unmanned systems, to control and implementation exhibiting a reliable and explainable level of autonomy and self-organization amidst the sudden and possibly extreme disturbances occurring in the uncertain and dynamic maritime environment.

The aim of Maritime Autonomous Vehicles: Methods and measurements is to embed design and practice in the digitalisation process, which is currently revolutionising engineering approaches in many domains, governed by model-based engineering paradigms and digital twin concepts. The coverage of the book connects design processes, good practices and methods, specifying their interfaces and standards for real-world measurements.

Written by a team of top-class international contributors, brought together by an expert in the field, this book provides an entry point into the hot topic of maritime autonomous vehicles - methods and measurements. The reader is invited to take a guided tour of the state-of-the-art in maritime robotics, and highlighted topics in coordination, communication, control, biomimetic design, and the real-world application of artificial intelligence tool chains for underwater datasets. The book presents a sophisticated simulation or surrogate model framework capable of addressing the necessity of maintaining holistically the interrelation of the many details real maritime environments need to have in order to be accurately described.

This thoughtful and authoritative work is intended to be a valuable source of information for researchers and engineers from academia and industry, working in the fields of navigation, robotics, radar, and of course maritime autonomous vehicles.

Advances in Underwater Communication and Networking

Fri, 12 Sep 2025 14:42:44 GMT

Underwater communication systems have been gaining significant interest over the past two decades in addressing various applications, ranging from the depths of the ocean to its surface. To implement applications such as oil monitoring, earthquake and tsunami detection, marine animal study and military surveillance, underwater communications are crucial in establishing reliable connections between sensor nodes.

Advances in Underwater Communication and Networking covers 6G-based underwater acoustic communications that integrate modern technologies such as software-defined networking (SDN), network function virtualization (NFV), non-orthogonal multiple access (NOMA), reconfigurable intelligent surfaces (RIS), unmanned aerial vehicles (UAVs), autonomous underwater vehicles (AUVs), and AI.

The book investigates NOMA as a solution to enhance spectral efficiency and user fairness in order to tackle acoustic band issues. This is followed by a detailed exploration of various machine learning and deep learning techniques for exploring underwater acoustic environments, optimizing acoustic signal transmission, and using hybrid intelligent models to power acoustic communications. The later chapters explore those few underwater applications that cover AI-based seismic monitoring, detection of tsunamis and earthquakes using AI-based models, and AI-based sonar image classification and analysis. In the final two chapters, the focus is on testing sound propagation in water and using various sonar systems to acquire underwater images and investigate real-life applications such as mine-detection, seabed mapping, and AUV navigation. Finally, a modelling scenario is developed and verified using the UPPAAL model checker for sonar-based subsystems.

Advances in Underwater Communication and Networking discusses a variety of recent concepts that will open new avenues for researchers in this field to explore underwater environments using 6G concepts and technologies.

Electromagnetics and Experimental Measurements of the Skin Effect

Thu, 21 Aug 2025 08:14:22 GMT

The skin effect is the tendency of alternating current (AC) to flow primarily near the surface of a conductor, rather than being evenly distributed, and this effect becomes more pronounced as the frequency of the AC increases. This is important because it increases the effective resistance of the conductor, leading to higher power losses and potential overheating. It can impact the design and performance of circuits, transmission lines (or waveguides), and antennas and is thus an important effect to be able to measure and control.

Although there is a very large corpus of literature on theoretical electromagnetism, there is much less written on experimental measurements, particularly for the skin effect. This monograph aims to fill the gap by emphasizing the experimental measurements and results obtained for the skin effect.

The book begins with three introductory chapters on the derivations of the equations of time dependent electromagnetic disturbances in which the author compares Maxwell's original approach with the present-day approach. Chapter 4 introduces the skin effect and gives an account of its importance. This is followed by 10 chapters covering more detailed theory and experimental measurements of the skin effect in solid and hollow cylindrical conductors. The final chapter describes methods of measuring the skin effect over a wide range of frequencies.

Electromagnetics and Experimental Measurements of the Skin Effect is written for an audience of electrical engineers, physicists, and anyone working in a field where electromagnetic techniques are widely employed. The book will also be of interest to advanced students in electromagnetics, physics and relevant areas of applied mathematics.

Darney's Circuit Modelling for Electromagnetic Compatibility, 2nd Edition

Thu, 21 Aug 2025 08:13:22 GMT

Electromagnetic interference or compatibility is a challenge faced by circuit designers across all areas of research, applications and industries, and is the subject of strict regulatory requirements. Darney's Circuit Modelling for Electromagnetic Compatibility, 2nd Edition shows how the analytical tools of circuit theory can be used to simulate the coupling of interference into, and out of, any signal link in the system being reviewed. This approach offers EMC testers and product designers a tool to work with at an early stage, before running expensive Faraday cage tests, which offers insight into whether a design is on the right track to achieving its design specification and so saving time and money.

The comparatively simple techniques explored in this book enable the design of equipment to be tailored to meet EMC requirements. A review of the construction of the wiring assemblies and the functions of the signals they carry allows critical links to be identified, then circuit modelling can be used to simulate the electromagnetic coupling mechanism of each critical link, allowing its performance to be analysed and compared with the formal requirements. Bench testing during product development allows any interference/compatibility problem to be identified and corrected, long before the manufactured unit is subjected to formal testing. The use of Mathcad and MATLAB® to perform analysis and assessment is also explored.

The first edition of the book was written by innovator in the field Ian B. Darney. This 2nd edition has been revised, expanded and updated by the author's former colleague and highly-experienced design engineer Chris M. Hewitt.

The book aims to equip electrical engineers working across all fields and sectors to investigate EMC problems using modelling techniques and general-purpose test equipment, enabling a more efficient and cost-effective circuit design process.

New Waves in Electromagnetic Technology

Mon, 11 Nov 2024 08:51:22 GMT

The concept for this book emerged from a webinar on Electromagnetic Waves: Successfully Surfing the Subject that the editor gave on behalf of the IET in June 2020. The concept was that experts in specialist areas of electromagnetics would write each chapter; providing insightful summaries of current developments within their specialisms, and then extrapolating these existing trends in a logical and reasoned fashion to forecast the future technological developments in their fields. The challenge was for them to look ahead by anything up to a century or more.

This volume presents the fruits of this plan, by focusing on current and forthcoming trends in ten of the most exciting and important areas of technological development involving the field of electromagnetics.

The book particularly addresses wireless power transfer, magnetic confinements fusion, the applications of metamaterials to improve antennas, lenses and cloaking technologies, powerful superconducting motors, applications of magnetic levitation, electrostatic dissipation in healthcare, electromagnetic propulsion for spacecraft, advances in liquid crystal displays, advanced particle accelerators and technological applications of magnetic monopoles.

It is an important consequence of the Maxwell Equations, which constitute the theoretical framework of electromagnetics, that accelerating or oscillating a charge generates a wave in the electromagnetic field. In a parallel fashion, this book aims to lead the charge in making waves in the field of electromagnetic technology.

New Waves in Electromagnetic Technology is a valuable resource for researchers in the electromagnetics community who are seeking perspectives on the leading edge of scientific thought and a long view on possible future directions in the field.

Recent Advances in High-Power Electromagnetics

Mon, 16 Sep 2024 09:19:44 GMT

We live in a modern world powered by large, complex systems, including financial markets, communication networks, transportation networks, and security infrastructure.

This book explores recent advances in HPEM sources, electromagnetic compatibility (EMC), strategies for protecting against intentional electromagnetic interference (IEMI) and detection and mitigation of these threats.

This book is an edited selection of invited papers that have been updated and expanded from the 2022 GlobalEM Conference. It offers an in-depth overview of the state of the art in high-power electromagnetics, including high-power microwave and ultrawideband sources, intentional electromagnetic interference, electromagnetic compatibility, and detection methods for IEMI threats.

The book will help readers working in high-power electromagnetics and related fields to:

Understand the capabilities of modern HPEM sources;
Understand the threats represented by HPEM on modern critical infrastructures, systems, and equipment;
Identify the coupling mechanisms of different HPEM sources in different scenarios;
Identify the efficacy of shielding, filtering, hardening and other protection mechanisms.

Multidimensional Radar Imaging

Thu, 01 Aug 2024 13:10:32 GMT

Increasing the performance of radar imaging systems will directly improve the effectiveness of automatic target recognition (ATR) systems. New ideas and solutions have been proposed in the recent NATO SET-250 Research Task Group (RTG) on multi-dimensional radar imaging, which initiated its activities in March 2017 and concluded them in October 2021. The goal of the SET-250 was to further develop systems and algorithms by using radar systems with extended dimensionality, such as multi-frequency, multi-polarisation and multi-view/multi-pass.

In view of the increasing number of drone-like platforms, multi-dimensional radar needs to be assessed and compared against mono-dimensional radars in terms of their ability to provide valid support for classification and recognition of such targets. One of the major efforts that has been made within the RTG has been the organisation and execution of the RAF Spadeadam Trials, which have seen the employment of four different airborne radar systems. A range of unique results were obtained that are summarised in the various chapters of this book.

This second volume of Multidimensional Radar Imaging contains declassified material that was generated within SET-250 and is key reading for anyone involved in researching or developing SAR radar imaging systems.

Radar Array Design using Optimization Theory

Mon, 08 Jul 2024 12:16:18 GMT

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.

This book provides an overview of radar beampattern synthesis based on optimised array design. Some of the most challenging application fields are explored, including phased array beampattern, multiple input multiple output (MIMO) beampattern in the presence of clutter, jamming, and congested environments. Innovative and sophisticated instruments from optimization theory, such as alternating direction method of multipliers (ADMM), coordinate descent technique, semidefinite relaxation, rank-one matrix decomposition, Lagrange duality theory, fractional programming, convex approximation, Pareto optimization, and machine learning (ML) are framed in the context of radar array design.

Providing a rigorous mathematical approach corroborated with a wealth of numerical study cases, chapters emphasize both theoretical results and practical applications, demonstrating the potential benefits achievable in radar array design through the utilization of modern optimization theory. A common list of symbols and extensive cross referencing has been undertaken so that the related material can be easily found. The cross-fertilization of recent research and discoveries in optimization theory is explored.

Radar Array Design using Optimization Theory is intended for systems engineers and their managers within the aerospace and defense sector, technical personnel in procurement agencies and their advisory teams, as well as academic researchers and students pursuing MSc and PhD degrees in signal processing, electrical engineering, and optimization theory.

Darney's Circuit Theory and Modelling

Thu, 09 Nov 2023 10:22:39 GMT

The equipotential earth is a fundamental requirement of circuit theory, because it dramatically reduces the complexity of the mathematics required to simulate a circuit. Unfortunately, in the real world, no such equipotential earth exists, nor can it ever do so, which means simulating a circuit to evaluate its electromagnetic compatibility (EMC) and susceptibility to electromagnetic interference (EMI) is largely dependent on using the Maxwell equations. The Maxwell equations are inherently complex, however, and so have high processing power requirements and, as with all complex systems, there is a propensity to generate and magnify errors.

Fortunately, the models provided in this book require far less processing power, as the mathematics required is far less complex than that of the Maxwell equations. These models are explained in a simple and straightforward manner, and can be used at the developmental stage of a project and redeployed in the testing stage before the manufacturing and product deployment stages are implemented.

A review of the relationship of circuit theory with electromagnetic theory identifies a way of augmenting these analytical tools, and this enables circuit models to be developed to simulate all forms of EMI, thus effectively updating and extending circuit theory.

The technique described in this book can be used to analyse all the mechanisms involved in the propagation of EMI. This approach avoids the need for endless debate on the topic of ground philosophy. Equally, it avoids the need to invoke the complexities of electromagnetic computation.

The book is aimed at electrical and electronic design engineers and EMI/EMC design consultants.
