Vehicular Joint Radar-Communications
Abstract: Recent interest in integrated sensing and communications (ISAC) has led to the design of novel signal processing techniques to recover information from an overlaid radar-communications signal. In this talk, we focus on the recent signal processing strategies and challenges associated with the development of sensing and communication systems that coexist with the vehicles and road infrastructure deployed in a given area. We consider a broad definition of coexistence, which covers joint communication and sensing, collaborative communication and sensing, and also interference. We consider an aspect of the coexistence paradigm where the two systems support each other beyond interference mitigation such as sensor-aided communications and communications-aided sensing. This opens up the avenue for the development of multivehicle sensor fusion strategies. We describe recent works that define topologies for combining radar and communication functionalities into the same equipment, drawing on the spectrum scarcity and possible gains from the reuse of resources. At higher frequencies, the complexity of the ISAC transceiver architectures requires the use of deep learning models for processing the received signals. In particular, we focus on the joint design of a waveform to mitigate interference, including communications-centric waveforms (OFDMA and 802.11ad), radar-centric waveforms (PMCW), or unified waveforms achieving optimal trade-offs between the two systems.

Biography: Kumar Vijay Mishra (S’08-M’15-SM’18) obtained a Ph.D. in electrical engineering and M.S. in mathematics from The University of Iowa in 2015, and M.S. in electrical engineering from Colorado State University in 2012, while working on NASA’s Global Precipitation Mission Ground Validation (GPM-GV) weather radars. He received his B. Tech. summa cum laude (Gold Medal, Honors) in electronics and communication engineering from the National Institute of Technology, Hamirpur (NITH), India in 2003. He is currently Senior Fellow at the United States Army Research Laboratory (ARL), Adelphi; Technical Adviser to Singapore-based automotive radar start-up Hertzwell and Boston-based imaging radar startup Aura Intelligent Systems; and honorary Research Fellow at SnT - Interdisciplinary Centre for Security, Reliability and Trust, University of Luxembourg. Previously, he had research appointments at Electronics and Radar Development Establishment (LRDE), Defence Research and Development Organisation (DRDO) Bengaluru; IIHR - Hydroscience & Engineering, Iowa City, IA; Mitsubishi Electric Research Labs, Cambridge, MA; Qualcomm, San Jose; and Technion - Israel Institute of Technology.
Dr. Mishra is the Distinguished Lecturer of the IEEE Communications Society (2023-2024), IEEE Aerospace and Electronic Systems Society (AESS) (2023-2024), IEEE Vehicular Technology Society (2023-2024), and IEEE Future Networks Initiative (2022). Dr. Mishra has received numerous best paper awards, fellowships, and other accolades. Dr. Mishra is Chair (2023-present) of the Synthetic Apertures Technical Working Group of the IEEE Signal Processing Society (SPS) and Vice-Chair (2021-present) of the IEEE Synthetic Aperture Standards Committee, which is the first SPS standards committee. He is the Vice Chair (2021-2023) and Chair-designate (2023-2026) of the International Union of Radio Science (URSI) Commission C. He is an Associate Editor for IEEE Transactions on Aerospace and Electronic Systems, and he has been a lead/guest editor of several IEEE special issues. His research interests include radar systems, signal processing, remote sensing, and electromagnetics.
