Ultrawideband Short-Pulse Radio Systems

by Vladimir I. Koshelev (Author), Victor P. Belichenko (Author), Yury I. Buyanov (Author)

This resource provides a comprehensive treatment of the methods, analysis, and practice of impulse and ultrawideband (UWB) systems. Sources, antennas, propagation, electromagnetic theory, and actual practical systems are explored. This book provides novel perspective on impulse and short-pulse wireless engineering along with practical guidance on how to build antennas and radio hardware for high-power impulse signals. Theoretical and experimental results in the time-frequency domain are presented.

The book explains and discusses the scattering of UWB electromagnetic pulses by conducting and dielectric objects. Impulse responses of objects and propagation channels are explored with details of signal models and their spectral characteristics and uses of regularization of a Kramers-Kroning type relation for estimating transfer functions. Readers gain insight into the development of high-power sources of UWB radiation with megavolt effective potential on the base of combined antenna arrays excited with bipolar voltage pulses. This in-depth volume includes chapters on receiving antennas, transmitting antennas, and antenna arrays along with details on high-power UWB radiation sources as well as problem sets.

Review
The book gives a broad overview of theoretical, implementation, and application aspects of short-pulse ultra-wideband (UWB) technique in microwave sensing and communications with special emphasis on radar issues. It is written for students, RF-engineers and researchers with background in undergraduate mathematics and electromagnetic wave propagation. It is not only a useful tool for newcomers and experienced engineers active in time domain electromagnetics but also for all those microwave engineers who want to broaden their view from the traditional sinewave technique to methods which apply more complicated waveforms.
The book examines and analyses all the essential components of an ultra-wideband transmission path from the generation of short electromagnetic pulses over their radiation, propagation and scattering to their reception and post-processing for target detection and recognition. Considerable attention was paid for solving boundary value problems related to the radiation and reception of UWB pulses, their propagation in media, and their scattering by conductive and dielectric objects. In order to illustrate the variety of possible applications, the authors introduce many examples ranging from real-time position finding or emergency car brake via intelligent transport systems, internet of things to medical engineering, search and rescue and many others. –Professor Juergen Sachs, Faculty of Electrical Engineering and Information Technology, Technische Universität Ilmenau

This book provides a comprehensive treatment on the theory and practice of ultrawideband electromagnetic impulse wave transmitting and receiving systems. Theoretical treatment of radiation, propagation, and scattering of impulse waves in the time domain provides a unique perspective and physical insight that cannot be easily obtained from traditional frequency-domain analysis. Transfer functions for elementary impulse transmitting and receiving antennas and their extension to array antennas present a quantitative description of impulse-preserving capabilities. Combined electric- and magnetic-type antennas provide a unique approach to antenna miniaturization. Treatment of high-power sources completes the description of a practical system. Readers, both professionals and students alike, will find invaluable resources in this book on ultrawideband impulse systems and benefit from the authors' extensive experience especially with high-power systems. –Do-Hoon Kwon, Department of Electrical and Computer Engineering, University of Massachusetts Amherst
