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.
This text attempts to give the reader an understanding of the key
developments in moment methods and the early history of this
development. It provides over 45 key papers in the field, many of
which are from non-IEEE sources.
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.
The material presented in this book is intended to provide the
reader with a practical treatment of Weibull distribution as
applied to radar systems. Topics include general derivation of
Weibull distribution, measurements of Webull-distributed clutter,
comparison of Webull distribution with various distributions
including Rayleigh, gamma, log-normal and k- distributions,
constant false alarm rate (CFAR) detectors for Weibull clutter,
non-parametric CFAR detectors, and signal detection in the time and
frequency domains. In particular, the Akaike Information Criterion
(AIC), which is a rigorously mathematical fit of the hypothetical
distribution to the data, is emphasised. This book is written
primarily for radar engineers. It is hoped that it will also be of
value to teachers and graduate students and of interest to all who
are working with Weibull distribution in various fields.
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.
This is a comprehensive book about modern radar techniques,
describing systems and methods at the college and graduate student
level. It covers radar principles, radar technology and the
application of that technology. This book starts with Radar Cross
Section (RCS) simulation and radar frequency synthesisers,
describes a manipulation of RCS with plasma, and develops a
millimetre wave frequency synthesiser for radar systems. Next,
multi-pulse performance evaluation of adaptive detection of
fluctuation radar targets and a C-band radar over an urban area are
introduced, followed by the interpolation of the radial velocity
data from coastal HF radars. At the finish, three-dimensional
synthetic aperture radar (SAR) mechanisms and imaging is
introduced, followed by GPU-based SAR raw data simulation for a
complex three-dimensional scene. This book will be of practical use
to engineers, technicians, planners, specifiers, and managers who
work with radar systems and with systems containing radars and
radar technology.

micro-Doppler sensors. Detailed MATLAB source codes for simulation
of radar backscattering from targets with various motions are
provided, along with source codes for generating micro-Doppler
signatures and analyzing characteristics of targets.
