Περίληψη διάλεξης:

In civilian applications, there is increasing interest in networked radars that are cheap and have small form factors, yet they enable reliable surveillance of an area. Unfortunately, these requirements are competing in nature. A networked radar is a configuration of transmit and receive antennas, in which target estimation is achieved by jointly processing the signals from all receive antennas. This processing can be done at a fusion center, which collects the measurements of all receive antennas, possibly in a wireless fashion. Reliable surveillance requires collection, communication and fusion of vast amounts of data, which involves significant power and bandwidth overhead.

The talk will present a new networked MIMO radar system that relies on advanced signal processing techniques, such as sparse sensing and matrix completion (MC-MIMO radar), in order to achieve an optimal tradeoff between reliability and cost. MC-MIMO radars achieve “super-resolution'' in the angle, Doppler and range space, while limiting the amount of data measured and transmitted by each sensor through the network.

Athina Petropulu received her undergraduate degree from the National Technical University of Athens, Greece, and the M.Sc. and Ph.D. degrees from Northeastern University, Boston MA, all in Electrical and Computer Engineering. Since 2010, she is Professor of the Electrical and Computer Engineering (ECE) Department at Rutgers, having served as chair of the department during 2010-2016. Before that she was faculty at Drexel University. Dr. Petropulu's research interests span the area of statistical signal processing, wireless communications, signal processing in networking, physical layer security, and radar signal processing. Her research has been funded by various government industry sponsors including the National Science Foundation, the Office of Naval research, the US Army, the National Institute of Health, the Whitaker Foundation, Lockheed Martin and Raytheon.

Dr. Petropulu is Fellow of IEEE and recipient of the 1995 Presidential Faculty Fellow Award given by NSF and the White House. She has served as Editor-in-Chief of the IEEE Transactions on Signal Processing (2009-2011), IEEE Signal Processing Society Vice President-Conferences (2006 - 2008 ), and member-at-large of the IEEE Signal Processing Board of Governors. She was the General Chair of the 2005 International Conference on Acoustics Speech and Signal Processing (ICASSP-05), Philadelphia PA. In 2005 she received the IEEE Signal Processing Magazine Best Paper Award, and in 2012 the IEEE Signal Processing Society Meritorious Service Award for "exemplary service in technical leadership capacities". She was selected as IEEE Distinguished Lecturer for the Signal Processing Society for 2017-2018.
