UWB MicroDoppler Radar for human Gait analysis, tracking more than one person, and vital sign detection of moving persons

Abstract

Pulse Doppler radars using UWB technology are becoming very popular for their wide range of capabilities and applications. UWB waveforms are used for imaging in indoor environments, target localization and classification behind walls, and evaluating micro-Doppler signatures. UWB pulse Doppler radars provide range-time-frequency representation that provides both highly accurate range and micro-Doppler information. This representation is used for detailed human gait analysis, tracking more than one subject even behind walls, and respiration rate detection even for moving subjects. That can be very useful for remotely health monitoring. In this study we experimentally investigate applying UWB to tracking more than one human subject as well as detection of respiration rate of a moving person.
