Metamaterial Integrated Radar Sensors for Location Tracking and Vital Sign Detection

Abstract

This paper introduces two types of radar sensor architecture integrated with metamaterial (MTM) leaky wave antennas (LWA) that have been developed recently. The first architecture is a self-injection locked (SIL) radar sensor with MTM LWA, where the LWA is designed with-60° to +30° beam-steering angle when the frequency varies from 1.85 GHz to 2.85 GHz. The second one is MTM LWA-based homodyne radar architecture, where the LWA scans from-30° to +50° as the frequency varies from 24.3 GHz to 27.3 GHz. For proof-of-concept, two targets sitting at different places are chosen for vital sign detection by using the proposed two radar sensor architectures, respectively. Meanwhile, locations of these two targets can also be tracked accurately. Experimental results agree well with the ground truth, which verifies the validity of the proposed radar sensor architectures.
