Ultra-Wideband Surveillance Radar is an emerging technology for
detecting and characterizing targets and cultural features for
military and geosciences applications. To characterize objects near
and under severe clutter, it is necessary to have fine range and
cross range resolution. The resultant wide bandwidth classifies the
systems as ultra-wideband, requiring special treatment in system
technology and frequency allocation. This book explores several UWB
surveillance radar prototypes, including Hostile Weapons Locator
System (HOWLS), Multibeam Modular Surveillance Radar (MMSR), and
geoscience synthetic aperture radar (GeoSAR). These prototype
radars illustrated the early development of multi-mode capabilities
leading to modern radar systems. Based on the results of these
prototypes and recent radar technology publications a novel
multi-mode, multi-channel radar is presented and analysed. The book
begins with a history of airborne surveillance radar, then goes on
to provide systematic and detailed coverage of the following topics
and technologies: surveillance radar detection; surveillance radar
modes; UWB antennas; ultra-Wideband SAR processing; interferometric
radar modes; UWB ground moving target detection; UWB spectrum
compliance; and UWB multimode operation. The first book to cover
these new capabilities, this is an important reference for radar
engineers, especially those working in geosciences and military
applications. It is also relevant to academic and advanced
engineering researchers developing new radar technologies and
algorithms for image processing, as well as the advanced
electromagnetics research community.
In the entire book efforts has been made to explain the practical
application of modern ICTs for transfer of agriculture
technologies. I have focused on systematic presentation of various
ICT tools with their applications by different organizations. Deep
understanding of modern ICT tools and techniques would enable
extension workers, scientists, teachers, students and researchers
to work efficiently for wellbeing of the farming community. The
book will prove useful and informative for officials of government
and non-government organizations working for transfer of
agriculture technology; teachers and students of agriculture and
allied sectors; Officials of Krishi Vigyan Kendras and agriculture
universities; Scientist and researchers of agriculture extension
and rural development. Overall the book is constructive for
Teaching, Research and Extension in the agriculture and allied
fields.
This book begins with the history and fundamentals of optical fiber
communications. Then, briefly introduces existing optical
multiplexing techniques and finally focuses on spatial domain
multiplexing (SDM), aka space division multiplexing, and orbital
angular momentum of photon based multiplexing. These are two
emerging multiplexing techniques that have added two new degrees of
photon freedom to optical fibers.
Energy and power are fundamental concepts in electromagnetism and
circuit theory, as well as in optics, signal processing, power
engineering, electrical machines, and power electronics. However,
in crossing the disciplinary borders, we encounter understanding
difficulties due to (1) the many possible mathematical
representations of the same physical objects, and (2) the many
possible physical interpretations of the same mathematical
entities. The monograph proposes a quantum and a relativistic
approach to electromagnetic power theory that is based on recent
advances in physics and mathematics. The book takes a fresh look at
old debates related to the significance of the Poynting theorem and
the interpretation of reactive power. Reformulated in the
mathematical language of geometric algebra, the new expression of
electromagnetic power reflects the laws of conservation of
energy-momentum in fields and circuits. The monograph offers a
mathematically consistent and a physically coherent interpretation
of the power concept and of the mechanism of power transmission at
the subatomic (mesoscopic) level. The monograph proves
(paraphrasing Heaviside) that there is no finality in the
development of a vibrant discipline: power theory.
The lack of clear communication, especially internationally,
plagues the modern world in a variety of fields. Researchers and
practitioners within the modern networking and communication
industries strive to discover new and innovative ways for humans to
better contact one another. Strategic Innovations and
Interdisciplinary Perspectives in Telecommunications and Networking
provides emerging research exploring the theoretical and practical
aspects of network management and security, as well as applications
within computer science, mobile and wireless computing, and
multimedia technology. Featuring coverage on a broad range of
topics such as coding theory, mobile devices, and contextual
advertising, this book is ideal for students, researchers, social
media marketers, brand managers, networking professionals, and
engineers seeking current research on cross-disciplinary
applications of electrical engineering, computer science, and
information technology.
Substrate integrated waveguide (SIW) technology is a twenty-first
century transmission line that has evolved recently to open new
doors to the development of efficient circuits and devices
operating in the microwave and millimeter-wave frequency range.
Microstrip circuits and devices are inefficient at high frequency
applications and require very stringent manufacturing tolerances
when used to implement microwave and millimeter-wave components.
This is as a result of the fact that wavelengths are short at
higher frequencies. Waveguide circuits and devices are preferred
for higher frequency applications, but they are expensive and
difficult to manufacture. It is also very challenging to integrate
a waveguide device with planar devices in its vicinity. The SIW
bridges the gap between the traditional air-filled waveguide and
planar transmission lines such as microstrip. Practical Approach to
Substrate Integrated Waveguide (SIW) Diplexer: Emerging Research
and Opportunities is an essential reference source that discusses
the development of efficient circuits and devices operating in the
microwave and millimeter-wave frequency range through the use of
substrate integrated waveguides. Featuring research on topics such
as microstrip resonators, circuit model analysis, and quality
factor extraction, this book is ideally designed for researchers,
engineers, scientists, developers, scholars, practitioners,
educators, policymakers, and students.
Source Separation and Machine Learning presents the fundamentals in
adaptive learning algorithms for Blind Source Separation (BSS) and
emphasizes the importance of machine learning perspectives. It
illustrates how BSS problems are tackled through adaptive learning
algorithms and model-based approaches using the latest information
on mixture signals to build a BSS model that is seen as a
statistical model for a whole system. Looking at different models,
including independent component analysis (ICA), nonnegative matrix
factorization (NMF), nonnegative tensor factorization (NTF), and
deep neural network (DNN), the book addresses how they have evolved
to deal with multichannel and single-channel source separation.

innovative digitally based services that are helping improve the
quality and cost of healthcare for the elderly. This book evolved
from a recent multi-country and multi-disciplinary initiative
called Digital Health for the Ageing Population. This project
(2019-2021) aimed at promoting general awareness of digital health
for ageing populations with collaborative research across several
countries including Australia, Bangladesh, China, India, Japan,
Norway, The Netherlands, and USA. With its international scope and
detailed coverage of relevant digital methods and tools, this book
