It's radar. So it is emitting radio waves, with a tiny tiny percent of them bouncing back to the detector. So it can be detected and/or jammed. Assuming these devices work on a very narrow frequency range, it shouldn't be too hard to passively hear them coming. If detectors appear, these devices would become a serious liability for anyone looking to "storm" a residence.
