1. A flying craft comprising:

  • a plurality of antennas distributed around a fuselage of the flying craft and configured to emit signals rearwards from the flying craft with rectilinear polarization, the emitted signals being specific to each antenna, positions and dimensions of the antennas being configured such that the fuselage of the flying craft avoids by masking for at least a first one of the antennas reflections of the signal emitted by the first antenna off the ground or off lateral obstacles irrespective of a position of the flying craft; and

    a reception device comprising;

    a plurality of monopulse antennas pointed in a same direction of sighting and operating in orthogonal planes; and

    means for identifying and processing, separately, signals received from respective antennas of the flying craft, such that signals emitted by separate antennas are identified and processed separately, and for automatically detecting and rejecting received signals disturbed by reflections.
