Title
(EN) NARROW BEAM ANTENNA SYSTEMS WITH ANGULAR DIVERSITY
(FR) SYSTEMES D'ANTENNES A FAISCEAUX ETROITS PRESENTANT UNE DIVERSITE ANGULAIRE
Abstract
(EN)
A receiving system (100) is disclosed which includes at least one antenna (101) providing a plurality of antenna beams. A first processing branch (103) is included for processing a first plurality of signals appearing within a first plurality of antenna beams. The first processing branch (103) includes a plurality of delay paths (105) each receiving a one of the first plurality of signals from a corresponding one of the first plurality of antenna beams and applying a predetermined amount of delay thereto, the preselected amount of delay proportionate to the corresponding one of the beams. First processing branch (103) further includes a combiner (106) for combining the first plurality of signals after output from the plurality of delay paths (105). A second processing branch (104) is provided for processing a second plurality of signals appearing within a second plurality of the antenna beams.

L'invention concerne un système de réception (100). Ce système comprend au moins une antenne (101) produisant une pluralité de faisceaux d'antennes. Un premier branchement de traitement (103) est prévu pour traiter une première pluralité de signaux apparaissant dans une première pluralité de faisceaux d'antennes. Le premier branchement de traitement (103) comprend plusieurs lignes de retard (105), recevant chacune un signal de la première pluralité de signaux à partir d'un faisceau correspondant de la première pluralité de faisceaux, et y appliquant un niveau de retard prédéterminé, ce niveau étant proportionnel au faisceau correspondant parmi la totalité des faisceaux. Le premier branchement de traitement (103) comprend également un combineur (106) pour combiner les premiers signaux à leur sortie des lignes de retard (105). Un deuxième branchement de traitement (104) est prévu pour traiter une deuxième pluralité de signaux apparaissant dans une deuxième pluralité de faisceaux d'antennes.
