For someone who works with RF frequencies for communication of Internet of things applications this is a very impressive use of RF. The team from MIT have built a device that can emits RF through a wall which rebounds of of objects the other side and using sequential frames reconstructs a captured object. For moving individuals it looks like there is a substantial doppler effect on the rebounding waves which is interesting as I am planning to get to grips with the 10Ghz microwave sensor system that relies on the doppler effect and is no where near what MIT are working on. Here is a video of what they have achieved which I think is seriously impressive.
