Abstract (en)
[origin: EP0367656A1] The sum and difference channels of the IFF are obtained with the aid of the reflector of the radar illuminated by primary radiating elements 3 to 8 associated with the horn 1 of the primary source of the radar. Moreover, the signals from the IFF sum and difference channels are suitably mixed to obtain a decrease in the level of the crossed-polarisation signals. <IMAGE>
