WiFi探测技术

WiFi信号的多普勒效应的应用,一直是一个比较热门的研究方向。下图中的情景,已经被真实地在生活中得到实现,利用的就是你家里长年累月不关闭的WiFi! 伦敦大学的一个研究团队,通过室内WiFi信号多普勒效应无源雷达判断室内移动的人或物。这一研究在National Instrument’s NI Week 2015大会上,获得了射频通信的最具影响力大奖!此前麻省理工学院也曾发明类似设备,但其是凭借有源雷达(也就是能自身发出电磁波的传统雷达)来实现上述效果的。而伦敦大学的设备,则可以通过WiFi发出的信号,甚至还能捕捉到GSM、LTE的信号当作基础信号,再加上其他监督信号来共同捕捉目标物体发生的多普勒偏移。 虽然现在伦敦大学的设备还无法形成图像,但可以在设备上呈现一个随移动而改变位置的小点。通过调整参数,甚至用户还能捕捉到更细微的变化,比如手势的改变。
