Abstract: Ultra-wideband radars have been gaining more attention recently. The subject of this talk is to provide a brief introduction to short pulse ultra-wideband radar. The basic blocks of a UWB radar are described, explaining how they can generate a quasi-impulse response of the antenna in it environment. The talk will go on to discuss some various effects of such radars such as the effects of timing error and the effects of down range motion. The discussion will then be expanded to discuss a technique called time-modulation and its various benefits such as improved electromagnetic compatibility and rejection of range ambiguities. Finally, a preliminary handheld motion mapper prototype designed to show the range and direction of movement behind non-metallic walls will be discussed, including images collected while penetrating a variety of building materials.

Biographical Sketch: Mark A. Barnes has been an electrical engineer at Time Domain Corporation for nine years. In that time he has worked on the theory and practice of UWB propagation and link analysis, compliance engineering, antenna design, circuit design, system design, and signal processing for both communication and radar systems. He is currently serving as team leader and RF/E-mag. systems engineer for the radar development team. Currently, he is focused on developing a hand-held radar that maps motion within buildings for law enforcement applications.

Mr. Barnes has published ten papers on ultra-wideband technology and has several patents. He received his Masters of Science in Electrical Engineering from the Ohio State University where his research focused on ultra-wideband ground penetrating radar.

NOTES:

  1. We will eat from 11:00 - 11:45am and the talk will begin at 11:45am. All lunch will be dutch treat. The price for lunch is about $5.50 (cost subject to selection), and there is a $2 meeting room fee for all participants.

  2. The Redstone Officer's Club is located off of Goss Road on the Redstone Arsenal. Turn left before entering Gate 9 (Rideout Road entrance). Go about 1 mile on Goss road and you will see the sign. Turn left and continue about ¼ mile and you will see the building on your right.
