Abstract
(EN)
This radar device (100) is provided with an antenna (1) that radiates radio waves, and a radome (2) for the antenna (1). The radome (2) has a fiber reinforced plastic layer (3) that includes a plurality of first fiber bundles (4) composed of a plurality of first fibers (6) and a plurality of second fiber bundles (5) composed of a plurality of second fibers (7). The fiber reinforced plastic layer (3) is provided so that: the longitudinal direction of each of the first fiber bundles (4) is aligned in a direction orthogonal to the direction of polarization of the antenna (1);the longitudinal direction of each of the second fiber bundles (5) is aligned in a direction parallel to the direction of polarization; and the electrical conductivity of each of the first fibers (6) is greater than the electrical conductivity of each of the second fibers (7).

L'invention concerne un dispositif radar (100) pourvu d'une antenne (1) qui rayonne des ondes radio, et d'un radôme (2) pour l'antenne (1). Le radôme (2) comprend une couche plastique renforcée par des fibres (3) qui contient une pluralité de premiers faisceaux de fibres (4) composés d'une pluralité de premières fibres (6) et une pluralité de deuxièmes faisceaux de fibres (5) composés d'une pluralité de deuxièmes fibres (7). La couche plastique renforcée par des fibres (3) est disposée de telle sorte que : la direction longitudinale de chacun des premiers faisceaux de fibres (4) est alignée dans une direction orthogonale à la direction de polarisation de l'antenne (1) ; la direction longitudinale de chacun des deuxièmes faisceaux de fibres (5) est alignée dans une direction parallèle à la direction de polarisation ; et la conductivité électrique de chacune des premières fibres (6) est supérieure à la conductivité électrique de chacune des deuxièmes fibres (7).
