An Experimental Study of Through-the-Wall Radar for Lifesign Detection

摘要

In this study, an experimental study on Through-the-Wall radar imagery was accomplished for the purpose of imaging life-sign symptoms. The proposed system is based on a stepped frequency continuous wave radar with the help of a Vector Network Analyzer (VNA-Agilent E5071B ENA), antenna (C-band), and the control computer. Breathing and heartbeat information is extracted from the backscattering electromagnetic field exploiting a change detection routine. The experimental results show that both breathing and the heartbeat signatures from real human beings are gathered.
