Radar with beam agility, in particular for the function of detecting and avoiding obstacles

摘要

The device has a column antenna (111) including a network and another network (12) of radiation elements for respectively focusing an emission beam and a reception beam in orthogonal elevation and azimuth planes. Focusing of one of the beams is obtained in one of the plane by colored emission followed by formation of the beam. Focusing of the other beam is obtained in the other plane by formation of the latter beam. The emission is realized by grouping sub-networks of antennae at the emission to form a sum channel and a difference channel at the reception based on monopulse technique.
