This text is a hands-on guide to time-frequency transforms for radar imaging and signal analysis. It explores more efficient ways to: extract dispersive scattering features; detect and extract weak signals in noise; form clear radar images; estimate parameters and perform motion compensation; detect and track moving targets in the synthetic aperture radar; and analyze vibration and rotation induced micro-Doppler. This resource introduces an image formation algorithm based on time-frequency-transforms, showing its advantage over the more conventional Fourier-based image formation. Referenced with over 170 equations and 80 illustrations, the book presents algorithms that help improve the result of radar imaging and signal processing. Moreover, the authors discuss future trends in time-frequency to analyze micro-Doppler, and provide a newly developed time-frequency approach to radar signal and image processing to help solve problems associated with conventional approaches.

Since publication of the first edition in 1988 many significant advances have occurred in IC chips that have driven the hybrid packaging processes toward even higher densities and greater performance. The almost exponential increase in density, complexity, and performance of integrated circuits over the past ten years (for example, ASIC (Application Specific Integrated Circuit), VHSIC (Very High Speed IC), VLSIC (Very Large Scale IC), and ULSIC (Ultra Large Scale IC) have driven developments in the interconnect substrates culminating in what is now known as multichip modules (MCM). However, the fundamentals of design, fabrication, and testing of MCMs are essentially the same as for hybrid microcircuit. In the authors' opinion MCMs are extensions of hybrid circuits that can accommodate the new generation of high-speed high-performance chips.

In this revised edition they have therefore expanded their treatment of hybrid circuits without finding it necessary to change the fundamentals. They have included a separate chapter on multichip modules and throughout the book have included new and emerging materials and processes that are beginning to be used. Examples include: metal-matrix composites and aluminum nitride as substrate materials, plastic encapsulated microcircuits and chip-on-board as low-cost alternatives to hermetic sealed packages, atmospheric friendly cleaning solvents and methods, and advanced high I/O density quad flat packages (QFP) and ball grid array (BGA) packages. Since the first edition, there have also been tremendous advances in software programs for thermal and electrical analysis and these are also treated in this new edition.

The gripping, behind-the scenes story of one of the most sophisticated surveillance weapons ever created – and an existential threat to democracy and human rights.

Pegasus is widely regarded as the most powerful cyber-surveillance system on the market – available to any government that can afford its multimillion-dollar price tag. The system’s creator, the NSO group, a private corporation headquartered in Israel, boasts about its ability to thwart terrorists and criminals.

But the Pegasus system doesn’t only catch terrorists and criminals.

Pegasus has been used by repressive regimes to spy on thousands of innocent people around the world: heads of state, diplomats, human rights defenders, lawyers, political opponents, and journalists.

Virtually undetectable, the system can track a person’s daily movement in real time, gain control of the device’s microphones and cameras at will, and capture all videos, photos, emails, texts, and passwords – encrypted or not. Its full reach is not even known.

This is the gripping story of how Pegasus was uncovered, written by Laurent Richard and Sandrine Rigaud, the two intrepid reporters who revealed the scandal in collaboration with an international consortium of journalists. Their findings shook the world.

Tense and compelling, Pegasus reveals how thousands of lives have been turned upside down by this unprecedented threat, and exposes the chilling new ways governments and corporations are laying waste to human rights – and silencing innocent citizens.

This book fills in details that are often left out of modern books on the theory of antennas. The starting point is a discussion of some general principles that apply to all electronic systems and to antennas in particular. Just as time domain functions can be expanded in terms of sine waves using Fourier transforms, spatial domain functions can be expanded in terms of plane waves also using Fourier transforms, and K-space gain is the spatial Fourier transform of the aperture weighting function. Other topics discussed include the Discrete Fourier Transform (DFT) formulation of antenna gain and what is missing in this formulation, the effect of sky temperature on the often specified G/T ratio of antennas, sidelobe control using conventional and novel techniques, and ESA digital beamforming versus adaptive processing to limit interference. Presents content the author derived when first asked to evaluate the performance of an electronically scanned array under design with manufacturing imperfections and design limitations; Enables readers to understand the firm theoretical foundation of antenna gain even when they must start from well-known formulations rather than first principles; Explains in a straightforward manner the relationship between antenna gain and aperture area; Discusses the relationship between sidelobe control algorithms and aperture shape, how to take advantage of it, and what the penalties are; Shows the equivalence of Minimum-Variance, Distortionless Response (MVDR) and Space-Time Adaptive Processing (STAP) and how these algorithms can be used with ESA subarrays to mitigate interference.

This book presents the statistical theory of complex wave scattering and quantum transport in physical systems which have chaotic classical dynamics, as in the case of microwave cavities and quantum dots, or which possess quenched randomness, as in the case of disordered conductors - with an emphasis on mesoscopic fluctuations. The statistical regularity of the phenomena is revealed in a natural way by adopting a novel maximum-entropy approach. Shannon's information entropy is maximised, subject to the symmetries and constraints which are physically relevant, within the powerful and non-perturbative theory of random matrices; this is a most distinctive feature of the book. Aiming for a self-contained presentation, the quantum theory of scattering, set in the context of quasi-one-dimensional, multichannel systems, and related directly to scattering problems in mesoscopic physics, is introduced in chapters two and three. The linear-response theory of quantum electronic transport, adapted to the context of mesoscopic systems, is discussed in chapter four. These chapters, together with chapter five on the maximum-entropy approach and chapter eight on weak localization, have been written in a most pedagogical style, suitable for use on graduate courses. In chapters six and seven, the problem of electronic transport through classically chaotic cavities and quasi-one-dimensional disordered systems is discussed. Many exercises are included, most of which are worked through in detail, aiding graduate students, teachers, and research scholars interested in the subject of quantum transport through disordered and chaotic systems.

This book focuses on the microscopic understanding of the function of organic semiconductors. By tracing the link between their morphological structure and electronic properties across multiple scales, it represents an important advance in this direction. Organic semiconductors are materials at the interface between hard and soft matter: they combine structural variability, processibility and mechanical flexibility with the ability to efficiently transport charge and energy. This unique set of properties makes them a promising class of materials for electronic devices, including organic solar cells and light-emitting diodes. Understanding their function at the microscopic scale - the goal of this work - is a prerequisite for the rational design and optimization of the underlying materials. Based on new multiscale simulation protocols, the book studies the complex interplay between molecular architecture, supramolecular organization and electronic structure in order to reveal why some materials perform well - and why others do not. In particular, by examining the long-range effects that interrelate microscopic states and mesoscopic structure in these materials, the book provides qualitative and quantitative insights into e.g. the charge-generation process, which also serve as a basis for new optimization strategies.

Mapping and localization are two essential tasks in autonomous mobile robotics. Due to the unavoidable noise that sensors present, mapping algorithms usually rely on loop closure detection techniques, which entail the correct identification of previously seen places to reduce the uncertainty of the resulting maps. This book deals with the problem of generating topological maps of the environment using efficient appearance-based loop closure detection techniques. Since the quality of a visual loop closure detection algorithm is related to the image description method and its ability to index previously seen images, several methods for loop closure detection adopting different approaches are developed and assessed. Then, these methods are used in three novel topological mapping algorithms. The results obtained indicate that the solutions proposed attain a better performance than several state-of-the-art approaches. To conclude, given that loop closure detection is also a key component in other research areas, a multi-threaded image mosaicing algorithm is proposed. This approach makes use of one of the loop closure detection techniques previously introduced in order to find overlapping pairs between images and finally obtain seamless mosaics of different environments in a reasonable amount of time.
