Transponder 03
Transponder 03 : A device which relays electrical signals not necessarily in the same form or on the same frequency as received. It is used in some types of rawin systems to overcome the decrease of target signal strength due to range attenuation. The transponder, in such systems, consists of a transmitter and a receiver so designed that upon receiving a pulse of energy from the ground radar, it will generate a new pulse on a different frequency, and transmit it back to the ground station
