  • Secondary radar antenna operating in S mode
    Patent number: 5302953
    Abstract: This invention concerns a secondary radar antenna operating in S mode.The antenna comprises a row of columns (1) of radiating elements powered by a hyperfrequency distribution circuit (2) containing a summing channel (.SIGMA.), a difference channel (.DELTA.) and a secondary lobe suppression channel (.OMEGA.), each producing a radiation diagram. The antenna end columns (L, R) each produce at least one auxiliary radiation diagram offset with respect to the diagram produced by the summing channel and contributing with the other antenna columns (1) to the creation of the other three diagrams.Application: secondary radars in S modes in communication with a large number of aircraft per antenna revolution.
