Yes, that's true.. but this does not avoid the round-trip measurement...

Hi,
as far as I know interrogation requests are send on 1030MHz with a
higher bandwidth and a different modulation scheme.

Hi ,
just one comment : the interrogation is periodic and stable.. the request
is transmitted by a rotating antenna turning at constant speed. If you
can
get the direct path to the interrogation system,
you may estimate the
round-trip time and then when the interrogation pulse is sent
