Researchers at UC Santa Barbara Prof. Yasamin Mostofi’s lab have given the 1st demonstration of 3D imaging of objects through walls using ordinary wireless signal. The technique, which involves 2 drones working in tandem, could have a variety of applications, such as search-and-rescue, archaeological discovery and structural monitoring. “Our proposed approach has enabled unmanned aerial vehicles to image details through walls in 3D with only WiFi signals,” said Mostofi, a professor of electrical and computer engineering at UCSB...
