I love learning about nav aids on planes. One thing I didn't quite understand was the DME interrogation:
"To handle conflicting pulses, each aircraft deliberately jitters its interrogation timing at random, then keeps only replies at a constant lag after its own pulses."
Does this mean that the pulse pair itself was jittered? As in, plane A sends a pulse pair, say 10us between the pulses and plane B sends a pulse pair 20us apart.
The DME then responds with the same pulse pair delay and the planes listen then calculate the responding pulse pair to figure out which one is theirs?
