Interest in the applications of ultrawideband (UWB) radar systems is increasing rapidly all over the world. This is evident from the number of monographs recently published on the subject and from the many papers presented at international conferences on the general problems involved in UWB radar and on its promising new applications. Conventional (classical) methods seem to have exhausted their potential and studies in the field are undergoing a profound change. This book presents some of the novel approaches to radar system analysis now being investigated. A good source of information on UWB signals is their structural analysis in the time domain. This allows a greater understanding of the specific features of UWB radar systems, such as the properties of receiving and transmitting antennas, and various characteristics of near- and far-range target scattering fields. It is shown how the systematic application of numerical procedures can provide new results in the evaluation of UWB radar target responses. The authors do not try to cover all of the possible solutions to the problem of multidimensional representation of target responses; rather they aim to give a general understanding of the techniques of confluent analysis, computer holography and adaptive synthesis of antenna apertures. These methods have great potential for solving conventional radar problems in target detection and recognition, and they are sure to stimulate the use of UWB signals in many fields such as subsurface probing and ecological monitoring.

A distillation of technical material culled from key radar publications and conferences that have occurred over the past five years, this book provides access to the answers to common design problems with designer crib sheets. William Morchin has also written Airborne Early Warning Radar.

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. Modern direction finders, capable of measuring elevation angles as well as azimuth angles on the components of multi-ray wavefields, have become powerful tools for research in ionospheric physics and HF radio propagation. The complexity of the problem of resolving closely-spaced rays requires the combined use of wide aperture antenna arrays, multichannel receiving systems and sophisticated digital processing techniques. Published research papers over the last 12 years provide a rich source of information on the development of superresolution algorithms for use in radar, sonar, geophysics and spectral analysis, as well as radio direction finding. Dr Gething reviews the important methods and results, showing how some of the new techniques are related to the wavefront analysis methods described in the first edition. The text is illustrated with computer plots of model wavefields and contain important results on the loci of constant phase and amplitude, and on the statistical properties of bearing-error distributions for specified models. The collection and interpretation of ionospheric data for the purpose of mode identification, and the statistical theory of DF plotting algorithms, are also discussed. Wavefront analysis and superresolution may be regarded as extensions to classical array theory. The basic principles are widely applicable and should therefore be of interest to research workers in radar, sonar, radioastronomy and adaptive array theory, as well as HF radio direction finding.

This book is devoted to the description of optimum signal processing algorithms which can find useful applications in radar systems. The monograph collects about twenty papers written by the Editor and his colleagues. Structurally the collection of the papers is divided into four parts. The first describes the adaptive cancellation techniques of radar clutter; the second part addresses the challenging problem of finding the optimum detection schemes to deal with target and clutter signals having non-Gaussian probability density function, and any type of autocorrelation function. The third group of papers considers the problem of finding the optimum detection schemes for the case of netted multi-static radar systems. The last part is concerned with more general processing techniques used in radar systems for surveillance. The aim of this text is to provide a theory of radar signal processing at a level which can be useful to practising radar engineers for analysis and design purposes. The relevance and modernity of the topics described ensure that the book can also be used with benefit for specialised graduate courses in communications and electronic engineering at universities and colleges as well as in continuing education courses for graduate employees in industry.

Radar has become an essential factor in air and sea travel, has affected all areas of military science and, most important of all perhaps, has considerably influenced the progress of electronic engineering. This book is the first general history of radar to be published, and one which covers the independent but more or less simultaneous emergence of radar in several countries in the 1930s. Some of the earliest proposals for the use of radio waves to detect objects at a distance are first dealt with. The narrative ranges from the concepts of Nikola Tesler in 1900 and the experiments of Christian Hulsmeyer in 1904 right through, in chronological order, to the commercially sponsored experiments of the pre-war days. The historical events and the military influences, which shaped the ultimate development of radar in each country, are then considered. The book also sets out to explain the basic principles of radar and, where applicable, historical aspects of the evolution of these principles are dealt with. The study, while underlining the significance of the cavity magnetron, purposely restricts itself to the cavity magnetron era of radar. Abundant references, which could facilitate further research, are given.

A self-contained approach to DSP techniques and applications in radar imaging
The processing of radar images, in general, consists of three major fields: Digital Signal Processing (DSP); antenna and radar operation; and algorithms used to process the radar images. This book brings together material from these different areas to allow readers to gain a thorough understanding of how radar images are processed.
The book is divided into three main parts and covers:

* DSP principles and signal characteristics in both analog and digital domains, advanced signal sampling, and interpolation techniques
*
Antenna theory (Maxwell equation, radiation field from dipole, and linear phased array), radar fundamentals, radar modulation, and target-detection techniques (continuous wave, pulsed Linear Frequency Modulation, and stepped Frequency Modulation)
*
Properties of radar images, algorithms used for radar image processing, simulation examples, and results of satellite image files processed by Range-Doppler and Stolt interpolation algorithms

The book fully utilizes the computing and graphical capability of MATLAB? to display the signals at various processing stages in 3D and/or cross-sectional views. Additionally, the text is complemented with flowcharts and system block diagrams to aid in readers' comprehension.
Digital Signal Processing Techniques and Applications in Radar Image Processing serves as an ideal textbook for graduate students and practicing engineers who wish to gain firsthand experience in applying DSP principles and technologies to radar imaging.

Written by a prominent expert in the field, this authoritative resource considers radar parameters and how they affect ESM systems. It describes the ESM environment, including types of radar, pulse density, the latest radar developments and how they will be seen by ESM systems. Different types of ESM systems are described, with methods of calculation of Direction of Arrival (DOA) of pulses. Conventional wisdom about RF scan strategies for narrow-band receivers will be challenged and new methods (proven to be effective in trials) will be proposed. The book describes ESM Antenna separation, which plays a significant part in the generation of DOA errors, with examples of the effects for different situations. The book will explain the common phenomena seen in ESM systems with many examples of how to recognize issues in the ESM data and solutions for their mitigation. Techniques for visualizing ESM data and how to set up ESM trials will be given, including the simulation of the electromagnetic environment. The book also presents detailed calculations for generating emitter beam-shapes for use in simulations of pulse trains and the calculation of detection range will be useful for data analysts, trials engineers and system assessors, which are not published elsewhere. The identification of radars by ESM systems is considered in detail with ideas presented on how to generate an effective radar library.
