Talk Title: Millimeter-Wave Computational Imaging
Abstract: This talk gives an overview on mmWave computational imaging. Millimeter-wave (mmWave) imaging has many applications such as remote sensing, autonomous robotics, non-destructive testing, and security screening. Some recent imaging systems will be presented, including compressed sensing and sparse reconstruction to minimize the amount of mmWave hardware, an enhanced resolution stripmap mode (ERSM) that leverages emerging metasurface antennas to improve image resolution by up to 42%, and an orthogonal coded active illumination (OCAI) approach to mitigate hardware imperfections and improve sensitivity by more than 40 dB. Finally, I will present a partitioned inverse reconstruction algorithm, optimized for GPUs, that yields a speedup of up to 300x.
Biography: Andreas Pedross-Engel is a postdoctoral Research Associate in the Department of Electrical and Computer Engineering at the University of Washington, Seattle, WA, USA. He is also a co-founder of the millimeter-wave imaging firm ThruWave Inc. He received the Dipl.-Ing. degree and the Ph.D. degree from Graz University of Technology, Graz, Austria, in 2009 and 2014, respectively. His research interests include microwave and millimeter-wave imaging systems, wireless communications, and nonlinear- and mixed- signal processing. In 2018 he received the ASciNA Young Scientist Award from the Austrian Federal Ministry of Education, Science and Research. He is also the recipient of the CoMotion Commercialization Fellows Award from the University of Washington in 2017. Since 2017 he is a Senior Member of the IEEE.
