I was talking about this with a friend last night, and I'm very surprised that no one in the media has even mentioned a technology like ultrawideband through-wall imaging (https://ll.mit.edu/mission/space/Real-time%20Through-wall%20Imaging.pdf https://ll.mit.edu/mission/space/Real-time%20Through-wall%20...). I suspect that this or something similar is what was being attempted.
