This book presents the theory, analysis and design of microwave stepped-frequency radar sensors. Stepped-frequency radar sensors are attractive for various sensing applications that require fine resolution. The book consists of five chapters. The first chapter describes the fundamentals of radar sensors including applications followed by a review of ultra-wideband pulsed, frequency-modulated continuous-wave (FMCW), and stepped-frequency radar sensors. The second chapter discusses a general analysis of radar sensors including wave propagation in media and scattering on targets, as well as the radar equation. The third chapter addresses the analysis of stepped-frequency radar sensors including their principles and design parameters. Chapter 4 presents the development of two stepped-frequency radar sensors at microwave and millimeter-wave frequencies based on microwave integrated circuits (MICs), microwave monolithic integrated circuits (MMICs) and printed-circuit antennas, and discussestheir signal processing. Chapter 5 provides the electrical characterization and test results of the developed microwave and millimeter-wave stepped-frequency radar sensors. Finally, a summary and conclusion is provided.

Autorentext

Dr. Nguyen joined the Department of Electrical and Computer Engineering, Texas A&M University in December 1990, after working for more than twelve years in industry, and is currently the Texas Instruments Endowed Professor. He was Program Director at the National Science Foundation during 2003-2004, where he was responsible for research programs in RF electronics and wireless technologies. From 1979 to 1990, he held various engineering positions in industry, serving as a Microwave Engineer with the ITT Gilfillan Company, a Member of Technical Staff with Hughes Aircraft (now Raytheon), a Technical Specialist with Aeroject ElectroSystems, a Member of Professional Staff with Martin Marietta (now Lockheed Martin), and a Senior Staff Engineer and Program Manager with TRW (now Northrop Grumman). While in industry, he led numerous microwave and millimeter-wave activities and developed many microwave and millimeter-wave hybrid and monolithic integrated circuits and systems up to 220 GHz for communications, radar, and remote sensing. His research group at Texas A&M University is currently focusing on CMOS/BiCMOS RFICs and systems, microwave and millimeter-wave ICs and systems, and ultra-wideband devices and systems for wireless communications, radar, and sensing-developing not only individual components, but also complete systems including design, signal processing, integration, and testing. He has published more than 315 papers, written six books and six book chapters, and given more than 200 conference presentations and numerous invited presentations. Professor Nguyen was the Founding Editor-in-Chief of Sensing and Imaging: An International Journal published by Springer and the Founding Chairman of the International Conference on Subsurface Sensing Technologies and Applications.
