Dept. Electrical Engineering and Computer Science Seminar Series
Ultrawideband (UWB) Radar Systems and Their
Applications
Presented by: Prof. Aly E. Fathy
WHEN: Monday, September 29th, 12:30-1:30 pm
WHERE: Pangborn Hall, Scullen Room
Abstract
The prevalence of ultra-wide band (UWB) in wireless systems (e.g. communication, radar, positioning) has increased
greatly in the last decade following the ruling by the Federal Communications Commission to allow system operation
over the 3.1-10.6 GHz band. These systems utilize state-of-the-art technology both in the radio frequency (RF) front-end
and digital back-end. Difficulties exist in implementing these complex systems given the varying levels of complexity in
both the digital and analog devices of the system (e.g. transistor level, component level, and overall system level).
Additional complexity is added by antenna effects, phase center variation, and the UWB indoor channel environment. In
this presentation, we illustrate how it can be directly utilized for three distinct UWB systems: a through wall imaging
radar system, a high accuracy indoor positioning system, and a non-contact triage vital sign monitoring system.
Biography
Professor Aly E. Fathy (Fellow, IEEE) is a Professor and the Head of the Antennas Laboratory at the University of
Tennessee (UT), Knoxville. He holds 12 U.S. patents, and has authored numerous transactions and conference papers.
His current research interests include Direct Broadcast Satellite (DBS) Antennas, wireless reconfigurable antennas, seethrough walls, UWB systems, and high-efficiency high-linearity combining of digital signals for base-station amplifiers. He
has developed various microwave components/subsystems such as holographic reconfigurable antennas, radial
combiners, direct broadcast antennas, speed sensors, and low-temperature co-fired ceramic packages for mixed-signal
applications. He is an active member of the IEEE Microwave Theory and Techniques Society (IEEE MTT-S) International
Microwave Symposium (IMS) Technical Program Committee (TPC), the IEEE Antenna and Propagation Symposium, and
the IEEE Radio and Wireless Steering Committee. He was the general chair of the 2008 IEEE Radio Wireless Conference.
He was the recipient of five Sarnoff Outstanding Achievement Awards during his employment at the RCA Research
Laboratory, (1988, 1994, 1995, 1997, 1999), Gonzalez family research excellence award (2005), two research excellence
awards from the College of Engineering, University of Tennessee (2009, 2011), Lamar Alexander Chancellor’s Excellence
Award in superior teaching and scholarship in 2011, research and creative achievement award in 2013, and in 2014 he
was recognized by the Excellence in Graduate Mentoring and Advising award. He is a member of Sigma Xi and Eta Kappa
Nu.
