Through-the-Wall Imaging Using Wi-Fi Signals

摘要：

　　In this work,we investigate,for the first time,the high-resolution three-dimensional(3D)through-the-wall imaging using the everyday wireless communication signals,i.e.,Wi-Fi signals,in an indoor environment.We also provide physical insights into such imaging technique,which has been derived from the well-known Huygens principle.Experimentally,the data acquisition has been realized in a synthetic aperture way,and the classical back-propagation algorithm is employed to form the high-resolution imaging.Moreover,we use IEEE 802.11n protocol wireless router working at 2.4GHz,the bandwidth is 20MHz,in our experiments.It can be faithfully expected that such imaging technique can open an exciting new door for various practical applications including safety screening and others.
