Metamaterial Integrated Super-Regenerative Radar for High-Sensitivity Vital-Sign Sensing

Super-Regenerative Oscillator (SRO) architectures, traditionally used in wireless transceivers, have recently been developed for vital-sign detection. Owing to the intrinsic automatic gain control feature, compared with conventional radar sensor architectures, the SRO-based radar sensor can exhibit a very high sensitivity with a lower system complexity, as well as DC-offset and null-point immunity. This talk will introduce different designs of SRO radar sensors, including the use of a metamaterial (MTM) leaky wave antenna (LWA) for concurrent multi-target vital-sign sensing and location detection.
