Index.
Mikhail Cherniakov joined the Communications Engineering Group at the University of Birmingham in 2000, and is now Senior Lecturer in Communications, as well as head of the Microwave Integrated System Laboratory. His research here is dedicated to various aspects of bistatic radar, as well as the integration of wireless technologies. Previous to this he has been involved in a wide range of research projects, including defence electronics, and radar and mobile communication at the University of Queensland, Australia, and at the Moscow Institute of Electronics Engineering, Russia. Over the last 30 years, he has headed numerous lecture courses on Radar Systems, Satellite Communications, Digital Communiations and Advanced Communication Systems. He has written the book An Introduction to Parametric Digital Filters and Oscillators (Wiley, 2003), and over 140 technical papers.
"This book will be a specific interest to engineering working in this field. It provides an essential background to understand radar signal processing as well as state-of-art technologies, and could therefore serve as text for graduate-level radar engineering course. The book will also be very informative to engineering students as a postgraduate level, and it might also be useful as a reference book for radar engineering and scientists."
