Time of Flight Microwave Camera

Modern cameras cannot see through fog, in the dark, or through walls, which make tasks such as driverless vehicles and search-and-rescue difficult. Where visible-light fails, radio-waves can easily penetrate these obstructions, however, radar-imaging devices are complex, low-resolution, and unable to image certain geometries and angled surfaces. This paper takes a camera-like approach to microwave-imaging, resulting in a simpler camera architecture which can capture fuller 3D images through-walls.
