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.
基于开关的自注入锁定雷达数据融合算法
在本研究中,我们开发了一种基于开关的SIL雷达系统,用于非接触式人体生命体征检测。将来自人体背部多个独立天线的雷达信号进行融合,扩大有效测量面积,减轻体位效应。该系统成本低,只需要一个雷达和多个简单的面板天线,而不是多个雷达和专门的体耦合天线。实验和仿真结果表明,该系统在各种体位下均能提供良好的检测效果。
