New research shows 3D through-wall imaging using only two drones and Wi-Fi

This should get the tinfofil hat brigade nice and riled up. New research from the University of California Santa Barbara has shown it is possible to make a “high-resolution 3D through-wall imaging of completely unknown areas” using only basic Wi-Fi signals and two drones.

The concept is pretty straightforward but the tech behind it is fairly complex. One drone acts as the Wi-Fi broadcaster, and the other drone “reads” the signals and maps out the interior. Both drones follow multiple paths around the area until a satisfactory image is created.

The idea is to use this tech for “emergency response, archaeological discovery, and structural monitoring”.
