They've had "small" radar modules for a while, commonly used as microwave movement detectors[0] Also, here is the manufacturer brochure[1] [0] http://dangerous

- ChuckMcM 10y agoThe difference being Multi-Antenna Synthetic Aperture RADAR vs single antenna RADAR.
- wyager 10y agoPrecisely. You need synthetic aperture (or similarly complicated Fourier analysis) with multiple transceive pathways to get a good 3D model of the environment. It's very impressive that this project managed to miniaturize both the radio hardware and the computational hardware required for this. You need to perform FFTs very fast to make this work.
