1. An antenna comprising:

  • a first and a second linear sub-antenna;

    each having a plurality of sensors arranged so as to form first and second line portions, respectively, with each sensor generating a basic signal;

    wherein the angle between respective directional vectors of the first and second tangents to the midpoint respectively of the first and second line portions is between 30° and

    150°

    ;

    an antenna processing device forming a plurality of combined signals for each line portion, which signal is a combination of basic signals from the sensors of this line portion;

    a signal processing device generating useful combined signals by filtering the noise of the combined signals coming from each line portion;

    a device for calculating normalized correlation coefficients between the useful combined signals of the first line portion and the useful combined signals of the second line portion;

    a device generating a detection signal when a normalised correlation coefficient exceeds a detection threshold.
