Abstract
In this study, we develop a switch-based SIL radar system for non-contact human vital-sign detection. Radar signals from multiple independent antennas in the back of a person are fused to expand the effective measurement area and mitigate body position effects. The system is low-cost, requiring only a single radar with multiple simple panel antennas instead of multiple radars with specialized body-coupled antennas. Experimental and simulation results show that the proposed system can provide excellent results under various body positions.
