Lecture

Wireless Sensing of Humans

Description

This lecture covers Frequency Modulated Carrier Wave (FMCW) radar, explaining how chirps are used to measure time through frequency changes. It delves into the process of measuring range and distance using FMCW signals, mixers, and FFT. The lecture also explores the concept of phased arrays, detailing how analog and digital phased arrays work in radar systems. Additionally, it discusses the challenges of multi-path reflections and the innovative use of wireless signals to sense human body parameters like heart rate and breathing without physical sensors, showcasing the potential for non-intrusive healthcare monitoring.
