This definitive book supplies the information needed to specify and
design a multifunction array radar system. With minimal
mathematics, the book shows how radars smaller in aperture and
power can meet demands formerly conceived for the larger rotating
and phased array radars.

The Sixth Conference on Ultra-Wideband, Short-Pulse
Electromagnetics (UWB SP6), chaired by Eric Mokole of the United
States Naval Research Laboratory (NRL) and hosted by the NRL and
the United States Naval Academy (USNA), was held at the USNA in
Annapolis Maryland (USA) from 3-7 June 2002. UWB SP6 was part of
the AMEREM 2002 Symposium, chaired by Terence Wieting of the NRL.
AMEREM 2002 continued the series of international conferences that
were held in: Brooklyn New York at the Polytechnic University in
1992 and 1994; Albuquerque New Mexico in 1996 as part of AMEREM
'96; Tel-Aviv Israel in 1998 as part of EUROEM '98; and Edinburgh
Scotland in 2000 as part of EUROEM 2000. The next conference (UWB
SP7) will be held from 12-16 July 2004 at Otto von Guericke
University in Magdeburg Germany (EUROEM 2004) and will be chaired
by Frank Sabath. The purpose of these meetings is: to focus on
advanced technologies for the generation, radiation, and detection
of ultrawideband (UWB) short-pulse signals, taking into account
their propagation about, scattering from, and coupling to targets
and media of interest; to report on developments in supporting
mathematical and numerical methods; and to describe current and
potential future applications of the technology. The session topics
of UWB-SP6 included electromagnetic theory, scattering, UWB
antennas, UWB systems, ground penetrating radar (GPR), pulsed, .
power generation, time-domain computational electromagnetics, UWB
compatibility, target detection and discrimination, propagation
through dispersive media, and wavelet and multi-resolution
techniques.
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. The design, development and testing of radar signal
processing for maritime surveillance requires a very detailed
understanding of the characteristics of radar sea clutter and of
the combined target and clutter returns. This book provides an
updated and comprehensive review of the latest research into radar
sea clutter and detection methods for targets in sea clutter. The
emphasis is on understanding the characteristics of radar sea
clutter as observed with different radars, viewing geometries and
environmental conditions. This understanding is assisted by the
development of mathematical models that are used in the radar
design process. In recent years there has been an increased
interest in operating at higher altitudes, resulting in the sea
surface being illuminated with larger grazing angles than used in
traditional airborne surveillance platforms or ground-based
systems. There has also been significant research into bistatic
operation, including passive radars using illuminators of
opportunity. The use of coherent and multi-aperture systems in
maritime radar are also of increasing interest and these new
application areas are also covered in this book.
The essence of cryptology is the making and breaking of codes and
ciphers. This is the second volume of articles (the first was
titled Cryptologia yesterday, today and tomorrow ) culled from
Cryptologia (Rose-Hulman Institute of Technology, Terre Haute, IN).
The articles are divided into five sectio
Low probability of intercept (LPI) radar is increasingly critical
to covert surveillance, target tracking and stealth operations - as
is the capability to detect it. Now, the world's most authoritative
book on LPI emitter design and counter-LPI techniques explores the
latest advances in the field in a new edition complete with
ready-to-use MATLAB software simulations for every LPI modulation
in the book. Supported by 360 task-clarifying illustrations, the
book offers radar engineers expert guidance on the design of LPI
emitter and intercept receivers and the development of digital
signal processing techniques for detecting and classifying LPI
modulations. This titleincludes a CD-ROM! It contains valuable
MATLAB programs that help professionals design various LPI emitter
architectures and waveform modulations to help them with their
detection and classification work.
The first two international conferences on Ultra-Wideband (UWB),
Short-Pulse (SP) Electromagnetics were held at Polytechnic
University, Brooklyn, New York in 1992 and 1994. Their purpose was
to focus on advanced technologies for generating, radiating, and
detecting UWB, SP signals, on mathematical methods, their
propagation and scattering, and on current as well as potential
future applications. The success of these two conferences led to
the desirability of scheduling a third conference. Impetus was
provided by the electromagnetics community and discussions led by
Carl Baum and Larry Carin resulted in the suggestion that the UWB
conferences be moved around, say to government laboratories such as
Phillips Laboratory. Consequently the decision was made by the
Permanent HPEM Committee to expand AMEREM '96 to include the Third
Ultra-Wide Band, Short-Pulse (UWB, SP 3) with the Third Unexploded
Ordnance Detec tion and Range Remediation Conference (UXO) and the
HPEMINEM Conference in Albuquerque, New Mexico during the period
May 27-31, 1996. Planning is now underway for EUROEM '98 in June,
1998 in Tel Aviv, Israel. Joseph Shiloh is the conference chairman.
A fourth UWB, SP meeting is planned as a part of this conference
and Ehud Heyman will coordinate this part of the meeting. The
papers which appear in this volume, the third in the UWB, SP
series, update subject areas from the earlier UWB, SP conferences.
These topics include pulse generation and detection, antennas,
pulse propagation, scattering theory, signal processing, broadband
electronic systems, and buried targets."
Including a systematic introduction to the fundamental principles
of microwave radar, this text presents an extensive discussion of
radar imaging. It also features information on image
superresolution, automatic target recognition, moving target
indication, and space-time adaptive processing (STAP).
The most complete compilation of millimeter-wave theory and data
available, this book addresses those phenomenological
characteristics of radar clutter and propagation in the
millimeter-wave region that are of particular importance in the
design, test and permutation of millimeter-wave sensors. The text
provides in-depth information on both electromagnetic propagation
and clutter backscatter effects in the millimeter-wave region.
Nicholas C. Currie is also the editor of "Radar Reflectivity
Measurement: Techniques and Applications" and "Principles and
Applications of Millimeter-Wave Radar".
This is a reference work for EW engineers which is also intended
for university use in advanced undergraduate or graduate-level
courses in EW, radar, and aerospace systems. This text reviews the
fundamental concepts and physical principles underlying EW
receiving systems design analysis, and performance evaluation. The
main discussion focuses on radar signals in military applications.
Radar Principles for the Non-specialist, Third 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 multielement systems have been widely used in many fields of
astron omy and radio science in the last decades. This is caused by
the increasing demands on the resolution and sensitivity of such
systems over the wide range of the electromagnetic wavelengths,
from gamma up to radio. The ground-based optical and radio
interferometers, gamma-ray and X-ray or bital telescopes, antenna
arrays of radio telescopes and also some other radio devices belong
to scientific instruments using multielement systems. There fore,
the current problems of the optimal construction of such systems,
or precisely, those of searching for the best arrangement of the
elements in them, were formulated. A rather large number of
scientific papers, including those of the authors, is devoted to
these problems, and we believe that the time has come to integrate
the basic results of the papers into the mono graph. The offered
book consists of three parts. The first part is concerned with the
optimal synthesis of optical and radio interferometers of various
types and purposes; the synthesis of non-equidistant antenna arrays
is con sidered in the second part; and the methods for the
construction of coded masks for X-ray and gamma-ray orbital
telescopes are expounded in the third one. Since in the text
combinatorial constructions which are little known to astronomers
are used, the necessary information is given in the appendices.
Various tables containing the parameters of the systems consid ered
are also represented."
Modern airborne and spaceborne imaging radars, known as synthetic
aperture radars (SARs), are capable of producing high-quality
pictures of the earth's surface while avoiding some of the
shortcomings of certain other forms of remote imaging systems.
Primarily, radar overcomes the nighttime limitations of optical
cameras, and the cloud- cover limitations of both optical and
infrared imagers. In addition, because imaging radars use a form of
coherent illumination, they can be used in certain special modes
such as interferometry, to produce some unique derivative image
products that incoherent systems cannot. One such product is a
highly accurate digital terrain elevation map (DTEM). The most
recent (ca. 1980) version of imaging radar, known as spotlight-mode
SAR, can produce imagery with spatial resolution that begins to
approach that of remote optical imagers. For all of these reasons,
synthetic aperture radar imaging is rapidly becoming a key
technology in the world of modern remote sensing. Much of the basic
workings' of synthetic aperture radars is rooted in the concepts of
signal processing. Starting with that premise, this book explores
in depth the fundamental principles upon which the spotlight mode
of SAR imaging is constructed, using almost exclusively the
language, concepts, and major building blocks of signal processing.
Spotlight-Mode Synthetic Aperture Radar: A Signal Processing
Approach is intended for a variety of audiences. Engineers and
scientists working in the field of remote sensing but who do not
have experience with SAR imaging will find an easy entrance into
what can seem at times a very complicated subject. Experienced
radar engineers will find that the book describes several modern
areas of SAR processing that they might not have explored
previously, e.g. interferometric SAR for change detection and
terrain elevation mapping, or modern non-parametric approaches to
SAR autofocus. Senior undergraduates (primarily in electrical
engineering) who have had courses in digital signal and image
processing, but who have had no exposure to SAR could find the book
useful in a one-semester course as a reference.

The rapid development of electronics and its engineering
applications ensures that new topics are always competing for a
place in university and polytechnic courses. But it is often
difficult for lecturers to find suitable books for recom mendation
to students, particularly when a topic is covered by a short
lecture module, or as an 'option'. Macmillan New Electronics offers
introductions to advanced topics. The level is generally that of
second and subsequent years of undergraduate courses in electronic
and electrical engineering, computer science and physics. Some of
the authors will paint with a broad brush; others will concentrate
on a narrower topic, and cover it in greater detail. But in all
cases the titles in the Series will provide a sound basis for
further reading of the specialist literature, and an up-to-date
appreciation of practical applications and likely trends. The
level, scope and approach of the Series should also appeal to
practising engineers and scientists encountering an area of
electronics for the first time, or needing a rapid and
authoritative update. vii Preface The basic principles of radar do
not change, but the design and technology of practical radar
systems have developed rapidly in recent years. Advances in digital
electronics and computing are having a major impact, especially in
radar signal processing and display. I hope that this book will
prove a useful intro duction to such developments, as well as to
the underlying principles of radar detection."
This book clearly describes all the radar detection and jamming
equations you need to design and analyze search and track radars.
It reviews the hardware, theories, and techniques involved in
modern EW systems signal processing and discusses present and
future trends in EW technology.
A valuable resource for radar engineers and managers of all levels,
this revised edition provides an introduction to the capabilities
and limitations of radar, as well as a detailed advanced study of
key radar signal processing topics. The book explains the concepts
and theory of radar signal processing such as resolution,
ambiguities, antennas, waveforms, the theory of detecting targets
in noise and/or clutter, and tracking using data processing. It
also presents equations for the determination of maximum radar
range in free space and as affected by multipath and the horizon.
A resource like no other—the first comprehensive guide to phase unwrapping Phase unwrapping is a mathematical problem-solving technique increasingly used in synthetic aperture radar (SAR) interferometry, optical interferometry, adaptive optics, and medical imaging. In Two-Dimensional Phase Unwrapping, two internationally recognized experts sort through the multitude of ideas and algorithms cluttering current research, explain clearly how to solve phase unwrapping problems, and provide practicable algorithms that can be applied to problems encountered in diverse disciplines. Complete with case studies and examples as well as hundreds of images and figures illustrating the concepts, this book features: - A thorough introduction to the theory of phase unwrapping
- Eight algorithms that constitute the state of the art in phase unwrapping
- Detailed description and analysis of each algorithm and its performance in a number of phase unwrapping problems
- C language software that provides a complete implementation of each algorithm
- Comparative analysis of the algorithms and techniques for evaluating results
- A discussion of future trends in phase unwrapping research
- Foreword by former NASA scientist Dr. John C. Curlander
Two-Dimensional Phase Unwrapping skillfully integrates concepts, algorithms, software, and examples into a powerful benchmark against which new ideas and algorithms for phase unwrapping can be tested. This unique introduction to a dynamic, rapidly evolving field is essential for professionals and graduate students in SAR interferometry, optical interferometry, adaptive optics, and magnetic resonance imaging (MRI).
Epoch-making progress in meteorology and atmospheric science has
always been hastened by the development of advanced observational
technologies, in particular, radar technology. This technology
depends on a wide range of sciences involving diverse disciplines,
from electrical engineering and electronics to computer sciences
and atmospheric physics. Meteorological radar and atmospheric radar
each has a different history and has been developed independently.
Particular radar activities have been conducted within their own
communities. Although the technology of these radars draws upon
many common fields, until now the interrelatedness and
interdisciplinary nature of the research fields have not been
consistently discussed in one volume containing fundamental
theories, observational methods, and results. This book is by two
authors who, with long careers in the two fields, one in academia
and the other in industry, are ideal partners for writing on the
comprehensive science and technology of radars for meteorological
and atmospheric observations.
Space-time adaptive processing (STAP) is an exciting technology for
advanced radar systems that allows for significant performance
enhancements over conventional approaches. Based on a time-tested
course taught in industry, government and academia, this second
edition reviews basic STAP concepts and methods, placing emphasis
on implementation in real-world systems. It addresses the needs of
radar engineers who are seeking to apply effective STAP techniques
to their systems, and serves as an excellent reference for
non-radar specialists with an interest in the signal processing
applications of STAP. Engineers find the analysis tools they need
to assess the impact of STAP on a variety of important radar
applications. A toolkit of STAP algorithms and implementation
techniques allows practitioners the flexibility of adapting the
best methods to their application. In addition, this second edition
adds brand new coverage on "STAP on Transmit" and "Knowledge-Aided
STAP (KA-STAP). Market Radar systems engineers and managers; signal
processing engineers and managers; and researchers and academics
involved in these areas.
The quest for high resolution has preoccupied radio astronomers
ever since radio waves were first detected from space fifty years
ago. This venture was par ticularly stimulated by the discovery of
quasars, and led to the development of interferometer techniques
using baselines of transglobal dimensions. These meth ods have
become known as Very Long Baseline Interferometry (VLBI). Arrays of
radio telescopes situated all over the Earth (or even in space) are
regularly used for researches in radio astronomy, reaching
resolutions as small as a fraction of a milli arcsecond. The
technique also allows the measurement of the positions of the radio
telescopes to a few millimeters and so VLBI has become a major tool
in geodesy and the study of the rotation of the Earth. VLBI has now
passed the pioneer stage and is becoming a standard facility
available to astronomers and geodesists, requiring the coordination
of the operations of indpendently owned radio telescopes around the
world. In Europe observatories from England, Federal Republic of
Germany, France, Italy, Poland, Sweden and The Netherlands are
coordinated in their VLBI activity by the European VLBI Network
Consortium (EVN). The Programme Committee of the EVN allocates time
to scientific projects on a routine basis three times a year. The
Unites States has a similar arrangement of a network of independent
radio observatories, and joint experiments using 'Global Network'
are often made."
