Title
(EN) A DIVERSITY SCATTERING DEVICE AND METHOD FOR USING THE SAME
(FR) DISPOSITIF DE DIFFUSION DIVERSIFIÉ ET SON PROCÉDÉ D'UTILISATION
Abstract
(EN)
The invention relates to device (501) and method for repeating wireless electromagnetic signals from a first side (80) of a space divider (90) to a second side (81) of the space divider (90). The device (501) provides at least two discriminated communication channels (630, 631) at a first frequency range between the two spaces. The device (501) comprises a dual polarized repeater (500) comprising a dielectric member (303), and a set of conductive members (517) as a group of radiators (502). Said dual polarized repeater (500) is adapted to be installed into a discontinuity region (101) of the space divider (90) and provides an increment of a bistatic radar cross section through said discontinuity region (101) for a first incident signal (601') and for a second incident signal (601''). At least a part of said first incident signal (601') is scattered as a first beam (803) by said device (501), and at least a part of said second incident signal (601'') is scattered as a second beam (804) on the second side (81) of the space divider (90). Said dual polarized repeater (500) provides cross polarization discrimination for said first incident signal (601') cross polarization discrimination for said second incident signal (601'').

L'invention concerne un dispositif (501) et un procédé de répétition de signaux électromagnétiques sans fil d'un premier côté (80) d'un diviseur d'espace (90) à un second côté (81) du diviseur d'espace (90). Le dispositif (501) fournit au moins deux canaux de communication discriminés (630, 631) à une première plage de fréquences entre les deux espaces. Le dispositif (501) comprend un répéteur à double polarisation (500) comprenant un élément diélectrique (303), et un ensemble d'éléments conducteurs (517) en tant que groupe d'éléments rayonnants (502). Ledit répéteur à double polarisation (500) est conçu pour être installé dans une région de discontinuité (101) du diviseur d'espace (90) et fournit un incrément d'une section transversale de radar bistatique à travers ladite région de discontinuité (101) pour un premier signal incident (601Γ) et pour un second signal incident (601''). Au moins une partie dudit premier signal incident (601') est diffusée sous la forme d'un premier faisceau (803) par ledit dispositif (501), et au moins une partie dudit second signal incident (601'') est diffusée sous la forme d'un second faisceau (804) sur le second côté (81) du diviseur d'espace (90). Ledit répéteur à double polarisation (500) fournit une discrimination de polarisation croisée pour ladite discrimination de polarisation croisée du premier signal incident (601Γ) pour ledit second signal incident (601'').
