Opis

Presents another way to look at electromagnetic waves and radar technology by extending the present knowledge about conventional narrowband technology Defines ultra-wideband radar within the context of this guide Includes discussions and information specifically useful to systems and subsystems designers Serves as a general technical reference on UWB radar as well as a textbook for senior- or graduate-level engineering courses in UWB technology Uses more than 360 figures to complement the text This introductory reference covers the technology and concepts of ultra-wideband (UWB) radar systems. It provides up-to-date information for those who design, evaluate, analyze, or use UWB technology for any application. Since UWB technology is a developing field, the authors have stressed theory and hardware and have presented basic principles and concepts to help guide the design of UWB systems. Introduction to Ultra-Wideband Radar Systems is a comprehensive guide to the general features of UWB technology as well as a source for more detailed information.
