I do it using MMWave sensor, 60Ghz one. Want to have more of them but installation is a pain as these need to be mounted on ceiling so WiFi based sensor would be awesome!

Do you have a writeup about this somewhere? I'd love to know more.

You can buy them on Aliexpress for $5. YouTube and a cursory google search will give you many many options to choose from for examples and tutorials.

There are a lot of radar modules out there in the wild.

But not all of them are good for doing stuff like this.

You need full raw I/Q and DAC access to sweep the frequency.
