It's a bit more than a theoretical possibility. 5G requires cooperative MIMO. If you can do cooperative MIMO, you can build the type of radar I'm describing.

It's a bit more than a theoretical possibility. 5G requires cooperative MIMO. If you can do cooperative MIMO, you can build the type of radar I'm describing. I don't have insider knowledge, but this is something that has been openly talked about for over twenty years. I'd be shocked if someone doesn't have at least a working test system.
