This talk will present an overview of recent research in FUNLAB around the use of vehicular radar for advanced driver assistance systems (en route to a future vision of autonomous driving). Wideband (typically FMCW or chirp) radars are being increasingly deployed onboard vehicles as key high-resolution sensor for environmental mapping/imaging and various safety features. The talk will focus on the evolving role of radar `cognition’ in complex operating environments to address two important future challenges:
1. Mitigating multi-access interference among Radars (e.g. dense traffic scenario)
The talk will first illustrate the impact of mutual interference on detection performance in Chirp/FMCW radars and then highlight some multi-access protocol design approaches for effective resource sharing among multiple radars.
2. Contributions to radar vision via new radar hardware (MIMO radar) + associated advanced signal processing (Synthetic Aperture principles) as well as Convolutional Neural Network (`Radar Net’) based machine learning approach for enhanced object detection/classification in challenging circumstances.
Bio: Sumit Roy received the B. Tech. degree from the Indian Institute of Technology (Kanpur) in 1983, and the M. S. and Ph. D. degrees from the University of California (Santa Barbara), all in Electrical Engineering in 1985 and 1988 respectively, as well as an M. A. in Statistics and Applied Probability in 1988. He is currently Professor, Electrical & Comp. Engineering, appointed to a term Distinguished Professorship for Integrated Systems (2014-19); since Sep. 2020, he serves as a rotator for US Dept. of Defense’s Program Lead for Innovate Beyond 5G https://5g-to-xg.org. His research interests include fundamental design and evaluation of wireless communication and sensor network systems spanning a diversity of technologies and application areas: next-gen (5G & beyond) wireless LANs and cellular networks, heterogeneous network coexistence, spectrum sharing, software defined radio platforms, vehicular and sensor networking. He spent 2001-03 on academic leave at Intel Wireless Technology Lab as a Senior Researcher engaged in systems architecture and standards development for ultra-wideband systems (Wireless PANs) and next generation high-speed wireless LANs. During Jan-July 2008, he was Science Foundation of Ireland’s E.T.S. Walton Awardee for a sabbatical at University College, Dublin and also recipient of a Royal Acad. Engineering (UK) Distinguished Visiting Fellowship during summer 2011. He has served as IEEE Communications Society (ComSoc) Distinguished Lecturer and as Associate Editor for all the major ComSoc journals. He served 2 terms as (elected) member of Executive Committee, National Spectrum Consortium dedicated to efficient spectrum sharing between Federal and commercial networks and is the co-author of IEEE TAES 2016 Best paper award for work on Radar-Comm coexistence. He was elevated to IEEE Fellow by Communications Society in 2007 for ``contributions to multi-user communications theory and cross-layer design of wireless networking standards”.
