>multiple RF detection stations with synchronized clocks, to determine the difference in arrival time. The radio emissions all travel at the same speed through the air, the difference in arrival time can be used with some simple trig to figure out where the RF emitter is.
That's a fancy way to say 'triangulation'.
- fest 7y agoI believe it's technically trilateration, not triangulation.
- coretx 7y agoContemporary passive radar arrays are phase sensitive so it ain't that simple either.
- rmattes 7y agoIt would be triangulation if the system was measuring the arrival angles of the incoming signals. If the system relying solely on arrival time differences, it's likely doing something based on trilateration.
