Abstract
The invention relates to the transmission of radiophonic signals and signals required for interrogating targets, in secondary radar equipment. So as to prevent the antenna provided for transmitting radiophonic signals from being disturbed because of its proximity to the non-directional antenna of the IFF, this latter is used to transmit both the interrogation signals and the radiophonic signals, a hybrid coupler disposed in the transmission circuit transmitting in a totally different way the two kinds of signals.
