The invention relates to a cross antenna comprising linear sub-antennas and to the associated processing for airborne radar. More specifically, the invention relates to an antenna (1) comprising: first (2) and second (3) linear sub-antennas which are equipped with sensors (21-2M, 31-3N) forming first and second line segments and generating a basic signal (Si', Gj'), the angle between the directional vectors of the first and second tangents to the midpoint of the first and second line segments being between 30° and 150°; a device for emitting an electromagnetic signal at a frequency that is at least equal to 10 GHz; an antenna processing device (4, 5) forming combined signals (VSi, VGj); a signal-processing device (6, 7) generating combined useful signals (TSi, TGj); a device (8) for calculating the correlation coefficients ([Cij]) between the combined useful signals; and a device (8) for generating a detection signal ([Rij]) when a correlation coefficient exceeds a threshold. |
