论文摘要
本文使用配备了模式可重构天线的无线局部网络设备（WiFi）针对人类运动检测的问题。通过监视源自支撑横梁向导技术的智能天线的环境WiFi信号的身体诱导的变化来获得运动感应，从而使天线辐射模式将其引导到预定的感兴趣点。我们首先讨论信号和渠道状态信息（CSI）处理和消毒。接下来，我们描述基于到达角度（AOA）监测的运动检测算法。建议的算法在大型智能家庭环境中经过实验验证。
The paper targets the problem of human motion detection using Wireless Local Area Network devices (WiFi) equipped with pattern reconfigurable antennas. Motion sensing is obtained by monitoring the body-induced alterations of the ambient WiFi signals originated from smart antennas supporting the beam-steering technology, thus allowing to channelize the antenna radiation pattern to pre-defined spots of interest. We first discuss signal and Channel State Information (CSI) processing and sanitization. Next, we describe the motion detection algorithm based on Angle-of-Arrival (AoA) monitoring. Proposed algorithms are validated experimentally inside a large size smart home environment.
