... isn't that just how radar works? A radio emission is sent out, bounces off an object, and then detectors measure the difference?
The fact that this works from the sky is definitely new, but I think all radar is light speed by definition.
7 0 Replylooks like the innovation here is with using ELF spectrum which penetrates seawater

Really weird they went for the "lightspeed" angle tho
