This book contains nine chapters, progressing from an “Introduction to Ultrawideband, Short- Pulse Radio Systems” to “Transmitting, Receiving, and Arrays Antenna Design and Analysis.” It offers a comprehensive treatment of the methods, analysis, and practice of impulse and ultrawideband (UWB) systems and explores UWB sources, antennas, propagation, electromagnetic theory, and practical systems. It also includes practical guidance on how to build antennas and radio hardware for high-power wideband impulse signals and presents both theoretical and experimental results in the time frequency domain. Further, this book explains and discusses the scattering of UWB electromagnetic pulses by conducting and dielectric objects as well as the impulse response of objects; it also includes coverage of the propagation channel. The reader gains insight into the development of the high-power source of UWB radiation with megavolt effective potential on the base of combined antenna arrays. The book has been translated into English from Russian, with many listed references in Russian. This text covers both theory and practical information on UWB short-pulse radio systems. A UWB radio designer can use many of the examples as a starting point to ensure that he or she is beginning on the right foot. Various examples of test data, parameters, and charts can serve as checkpoint comparisons for an original design. Ultrawideband Short- Pulse Radio Systems is an extremely useful guidebook for any radio designer.
