X-ray eyes in the sky: Drones and WiFi for 3-D through-wall imaging | ScienceDaily

Researchers at UC Santa Barbara professor Yasamin Mostofi’s lab have given the first demonstration of three-dimensional imaging of objects through walls using ordinary wireless signal. The technique, which involves two drones working in tandem, could have a variety of applications, such as emergency 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. “This approach utilizes only WiFi RSSI measurements, does not require any prior measurements in the area of interest and does not need objects to move to be imaged.”
