IEEE AESS Distinguished Lecturer Talk
TITLE: Passive Through-Wall Human Sensing with WiFi
Presented by: Dr. Hongbo Sun, Agency for Science, Technology and Research (A*STAR), Singapore.
Organized by: OES-GRSS Newfoundland and Labrador Chapter (contact: Prof. Weimin Huang, Memorial University)
Date and Time: 14:00 (Newfoundland Time), 9 September, 2024
Location: CSF-1203, Memorial University

ABSTRACT: Through-wall human sensing is of high interest to both the Defense Department in counter-terrorism applications and the Home Affairs Department for civilian law enforcement purposes, particularly in the modern highly urbanized environment. Conventional active radar sensors possess good performance, however, at the expense of high cost and complexity of the transmitter/receiver design. This talk demonstrates the effectiveness of a passive through-wall human sensing technique using the opportunistic WiFi signal. With a simple software defined radio (SDR) receiver, the position of indoor WiFi access point is accurately localized and the Doppler/micro-Doppler of human motions inside the room are clearly detected. It is demonstrated that the WiFi-based passive radar is capable of detecting not only major motions such as walking and waving hand, but also very small human motions such as finger typing and breathing.
About the Speaker: Dr. Hongbo Sun received his B.Eng. and Ph.D. degrees from Nanjing University of Science and Technology, China, in 1997 and 2002 respectively, both in Electrical Engineering. He joined the School of Electrical and Electronic Engineering, Nanyang Technological University (NTU), Singapore, in 2002, as a Research Fellow. From 2004 to 2019, he was with Temasek Laboratories at Nanyang Technological University as Research Scientist, Senior Research Scientist, and Programme Manager (Urban Sensing). Since 2019, he has been with Institute for Infocomm Research (I2R), Agency for Science, Technology and Research (A*STAR), Singapore. He is currently a Principal Scientist and the Head of Satellite Communication & Sensing Division in I2R.
Dr. Sun has very wide range of research experience on radar systems, signal processing, phased array system, integrated sensing and communication, and satellite communication. He has authored/co-authored one book chapter and more than 80 technical papers in refereed journals and conference proceedings. Between 2004 and 2011, he served as the member of IEEE P1672 Working Group for drafting IEEE STD 1672 Ultrawideband Radar Definitions. He is the Associate Editor for IEEE Transactions on Aerospace and Electronic Systems and Electronics, and was the Guest Associate Editor for IEEE Geoscience and Remote Sensing Letters between 2015 and 2017. Previously he had ever served as the Chair of IEEE AESS/GRSS Joint Singapore Chapter for two terms (2016-2017 and 2022-2023), and TPC Members / Session Chairs of numerous IEEE international conferences. He was also the recipient of the Excellent Paper Award at the RADAR 2006 conference. Since 2020, he has been appointed as the IEEE AESS Distinguished Lecturer.
