IEEE Distinguished Lecture
Dr Hongbo Sun is a Principal Scientist and Head of the Satellite Communications & Sensing Division at the Institute for Infocomm Research (I2R), A*STAR, Singapore. His research covers radar systems, signal processing, phased array systems, integrated sensing and communication, and satellite communications. He has authored one book chapter and over80 technical papers. He is an Associate Editor for IEEE Transactions on Aerospace and Electronic Systems and has been an IEEE AESS Distinguished Lecturer since 2020.
Through-wall human sensing is highly valuable for counter- terrorism and civilian law enforcement, especially in modern urbanized environments. Conventional active radar performs well but requires costly, complex transmitter/receiver designs. This talk demonstrates a passive through-wall human sensing technique using opportunistic WiFi signals. With a simple software defined radio (SDR) receiver, the indoor WiFiaces point is accurately localized, and the Doppler/micro-Doppler of human motions are clearly detected. It is shown that the Wii based passive radar can detect not only major motions such as walking and waving hands, but also very small motions such as finger typing and breathing.

Passive Through-Wall Human Sensing with WiFi
