A new radar scanning system developed by researchers at the National Institute of Standards and Technology uses microwave scanner that can create real-time images and video of objects — even when they are hidden behind walls or moving at hypersonic speeds. The technology could potentially allow first responders to more easily find people in smoke-filled burning buildings, or to track speeding debris up in space. Seyedmohammadreza Faghih Imani, a Fulton Schools assistant professor of electrical, computer and energy engineering, who has studied microwave imaging, describes how this new technology expands the possibilities of what microwave imaging systems can do. Imani says it could lead to more effective microwave security scanners at airports and microwave imagers for self-driving cars, as well as microwave cameras that can fit into telephones.
