Scientists proposed a high-resolution 3D through-wall imaging of completely unknown areas, using only unmanned aerial vehicles and WiFi signals.
Some of the key features of our approach are as follows: 1) only WiFi RSSI measurements are used, 2) no prior measurements need to be made in the area of interest, and 3) the objects do not have to move to be imaged. Here, we briefly summarize our proposed approach and show sample experiments results.
