Discussion

Oliver Walter Jul 4, 2004:
Is the Abramptransponder receiving a radar signal that is pulsed and/or chirped (under the "gegebenenfalls" conditions)? (If yes, that would make it virtually certain that Gillian's reply is correct.)
Non-ProZ.com Jul 4, 2004:
Es handelt sich um ein Shuttle im Montagebereich
David Moore (X) Jul 4, 2004:
If we knew WHAT was travelling at high speed off a ramp - a rocket?? - we might have better ideas....

there are no googles for Abramptransponder, which doesn\'t help.

gives

Deramping
A technique to process chirped wide-band signals with limited receiver bandwidth. The first downconversion LO is replaced with a chirped signal with the same slope of the received one. The resulting output is a tone with an offset from the centre frequency proportional to the time offset between the two chirps. In this way, the bandwidth needed in the RX stages after Deramping is proportional to the width of the receive window and non to the chirp bandwidth itself.
Peer comment(s):

agree Oliver Walter : I'm not familiar with "deramping" but this page gives some confirmation: http://esapub.esrin.esa.it/bulletin/bullet83/fran83.htm

down-ramp or ramp-down transponder

I don't find even the term ramp in my fairly comprehensive Dictionary of Electronics, let alone down-ramp, ramp-down, or deramp.
So, my low-confidence suggestion is a shot in the dark.

I probably shouldn\'t have chirped up at all. Sounds like Gillian is onto something. (not \"on something\")
