Abstract (en)
The method involves dividing an antenna into a number (n) of adjacent parts. A number of elements of a divided signal are applied to the parts according to a predetermined phase law. On reception, a number of beams are formed simultaneously. Each beam formed has an angular width equal to n times the angular width for the complete antenna. The relative dephasing of the beams is because each beam follows a different law. The beams are displaced to cover the angular domain desired.
Abstract (fr)
Le procédé d'élargissement de l'invention consiste à diviser l'antenne radar en n groupes de colonnes de modules actifs (MA), à appliquer, en émission, une loi de phase linéaire différente à chaque groupe, et en réception à former n² faisceaux simultanés, chacun ayant la largeur angulaire nominale de l'antenne complète, et à déplacer globalement ces faisceaux pour couvrir le domaine angulaire dans lequel l'énergie a été rayonnée à l'émission. <IMAGE>
