Microwave radiation just isn‘t suitable for imaging people. Google for „diffraction limit“ to learn why. That‘s why the devices in this article, unlike millimeter wave scanners, can‘t create an image of the scanned subjects. (and it’s also the reason why why millimeter wave scanners make very blurry images). Instead, these detectors look for resonances in the emmitted spectrum. The article was a bit light on details, but this description sounds very much like an old school metal detector, rather than an imaging device.
