If you don't mind me asking why would you want to do this? We are working on technology for a "digital twin" and have not really thought about applying it to inside the home. What benefits are there of knowing where you/other people are around the home?

Good question, my main motivation is to learn more about how such a system would work. I am interested in signal processing and especially radar like systems so implementing one would be a fun experience.

In general, systems based on radar are trying to replace wearables for sleep states tracking, elderly fall detection etc. But I'm not sure yet what other applications it might have. The ability to track my location just seemed like a good first step.

If you don't mind wearing a Hololens all day, it orients itself by turning your entire surroundings into ~1m mesh blocks that serve as its internal map. As a bonus, you can retrieve the current mesh from the device's internal web server in order to visualize against it.

Cons: Wearing Hololens all day, spending thousands on a hobby project. :-/ Fascinating if you manage to borrow one though.

A smaller and less expensive V-SLAM option would be the Intel RealSense T265 camera.

Tracking accuracy can sometimes drift quite a bit with this if you’re not careful, but it can perform pretty well, especially if loop closing is enabled.

Even more fascinating, if they manage to wear it the whole day.

Thanks for the info! We are actually approaching it from a more computer vision angle. Think several RGBD sensors (kinect/structure) placed around your home and fusing the data into a real-time 3D model.

Interesting approach using radar for tracking, if you make any progress would be interested to hear about it.
