Am I understanding these correctly? They sound like basically using
a radar to measure VSWR. Send a pulse out, see what the response looks
like
Yes. If you send out the pulse and nothing comes back, the device you
sent it to is terminated correctly at the far end, so there is no
reflection. If it isn't terminated correctly you will see a return
pulse, upright or inverted, and if the device isn't correctly terminated
at the sending end you will see successive reflections, decreasing in
amplitude due to the losses in the device.
It's a rather attractive technique.
