Two Dimensional mmWave SAR Imaging by Professor Murat Torlak, UT Dallas
Friday, Apr 20
1 p.m. - 2 p.m. Location: ECSS 3.503

ABSTRACT:

Millimeter-wave (mmWave) imaging technology is one of the fastest growing technologies of this decade with wide range of applications including medical, automotive radars, and security screening. Millimeter-wave imaging techniques involve collecting the reflected wave data from targets in distinct dimensions. In this seminar, we describe novel image reconstruction algorithms, inspired by synthetic aperture radar (SAR) signal processing techniques used in remote sens-ing/surface mapping. In particular, we show 2D mmWave imaging using wideband (FMCW) mmWave sources. A prototyping X-Y imaging system utilizing commercially available 77 GHz radar sensors and high-speed mechanical scanner has been developed and tested.  Our prototype system will be described in detail along with various imaging results.

BIO:

Murat Torlak received M.S. and Ph.D. degrees in electrical engineering from The University of Texas at Austin in 1995 and 1999, respectively. Since August 1999, he has been with the De-partment of Electrical Engineering at University of Texas, where he has now been promoted to the rank of Full Professor. He spent the summers of 1997 and 1998 in Cwill Telecommunications, Inc., Austin, TX, where he participated in the design of a smart antenna wireless local loop sys-tem and directed research and development efforts towards standardization of TD-SCDMA for the International Telecommunication Union. He was a visiting scholar at University of California Berkeley during 2008. He has been an active contributor in the areas of smart antennas and mul-tiuser detection. His current research focus is on millimeter wave automotive radars, millimeter wave imaging systems, cognitive radios, and interference mitigation in radio telescopes. He served as an Associate Editor of IEEE Trans. on Wireless Communications during 2008-2013. He was the Program Chair of IEEE Signal Processing Society Dallas Chapter during 2003-2005. He is a Senior IEEE member. He has served on the Technical Program Committees (TPC) of the several IEEE conferences. He was the general chair of Symposium on Millimeter Wave Imaging and Communications in 2013 IEEE GlobalSIP Conference.
