SYSTEM OF INTEGRATION OF THE WAYS IN SUM AND DIFFERENCE I.F.F. IN A RADAR SURVEILLANCE ANTENNA

摘要

The invention relates to radar monitoring antennas comprising an identification system I.F.F. / P P The invention lies in the fact that the sum and difference channels of I.F.F. are obtained by means 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 of the sum and difference channels I.F.F. are suitably mixed to obtain a decrease in the level of cross-polarized signals. / P P The invention is applicable to surveillance radars with I.F.F.
