Method Uses Drones and WiFi to Enable 3D Through-Wall Imaging

WiFi signals are everywhere. Unmanned aerial vehicles (UAVs, or drones) are expected to become a larger part of everyday life. A new methodology was developed for high-resolution, 3D, through-wall imaging of completely unknown areas, using only WiFi signals and UAVs. The approach utilizes only WiFi received signal strength measurements, does not require prior measurements in the area of interest, and the objects do not have to move to be imaged.
