Portable Radar Systems for Life Activity Sensing, Anomaly Detection, and Human Tracking Video

Portable radar systems with embedded control and signal processing have the potential to improve the quality of service in many healthcare, human-computer interface, and internet of things (IoT) applications. This talk provides an overview of our recent research activities in developing smart microwave radar sensors based on advanced technologies including digital/RF beamforming, multiple-input and multiple-output (MIMO), synthetic aperture radar (SAR), inverse synthetic aperture radar (ISAR), automatic DC offset cancellation, and machine learning. A few radar systems operating in interferometry, Doppler, frequency-modulated continuous-wave (FMCW) and frequency shift keying (FSK) modes at 5.8 GHz, 24 GHz, and 120 GHz will be discussed. The unique features of FMCW- and FSK- mode operation will be compared. Case studies will be presented on bioengineering and Internet of Things (IoT) applications including life activity sensing and tracking, anomaly detection of a person with concealed weapons, and flood water monitoring.
