If you think of data that's one thing, but Radar a rather different one. You won't need to bump a scanning ray around, if you can simply detect changes in the static urban microwave background. You'd need many senders. Suppose those fit into lanterns, that have line of sight by definition. I'm fantasizing about MEDs emitting 26 GHz with 1GHz duty cycle, lol.
