Abstract
The disclosed broadening method consists in dividing the radar antenna into n groups of columns of active modules, applying, at transmission, a different linear phase law to each group and, at reception, forming n.sup.2 simultaneous beams, each having the nominal angular width of the complete antenna, and in shifting these beams as a whole to cover the angular domain in which the energy has been radiated at emission.
