Abstract
This work focuses on 3D RF imaging using an array of antennas. The antenna array transmits radio waves into a room, where they reflect off objects. By recording and processing the reflected waves that are received back at the antennas, a 3D image of the room can be created in real-time. One of the applications that this enables is gesture recognition. By imaging the motion of a person's hand, the antenna array can provide user input to an immersive reality system. Furthermore, the RF imaging system enables the environment to detect when a person is in the room, who they are, and what they are doing. This can be extended to allow the environment to monitor a person's vital signs in a non-intrusive manner. Over the past year, MATLAB simulations have been developed of various antenna array configurations to take both static 3D images and motion-detection 3D images. A physical testbed is currently being used to verify these simulations.
