The invention relates to a cross antenna system comprising linear sub-antennas and to the associated processing. More specifically, the invention relates to an antenna system (1) comprising several antennas, each antenna consisting of first (2) and second (3) linear sub-antennas which are each equipped with a plurality of sensors (21-2M, 31- 3N) forming respective line segments and generating a basic signal (Si', Gj'), the angle between the directional vectors of the tangents to the midpoint of the first and second line segments being between 30° and 150°. The sub-antennas of the different antennas form a reception lobe including essentially one plane. The invention also comprises a device (8) for calculating the correlation coefficients ([C<SUB>ij</SUB>]) between the combined useful signals originating from the line segments of one antenna; and a device (8) for generating a detection signal ([Rij]) when a correlation coefficient exceeds a pre-determined threshold. |
