Title
(EN) APPARATUS AND METHOD FOR MITIGATING MULTIPATH EFFECTS AND IMPROVING ABSORPTION OF AN AUTOMOTIVE RADAR MODULE
(FR) APPAREIL ET PROCÉDÉ POUR ATTÉNUER DES EFFETS DE TRAJETS MULTIPLES ET AMÉLIORER L'ABSORPTION D'UN MODULE RADAR POUR VÉHICULE AUTOMOBILE
Abstract
(EN)
A radar system and method with reduced multipath effects include a first component of a radar sensor module on which at least one antenna element is formed, the at least one antenna element having a surface at which radar radiation is received or transmitted, the at least one antenna element having a radiation aperture. A second component in proximity to the antenna element such that a portion of the radar radiation impinges on the second component comprises an angled surface forming an angle with the surface of the antenna element. The angled surface of the second component comprises a texture such that when the portion of the radiation impinges on the angled surface, the amount of multipath signal propagating through the radiation aperture of the antenna element is reduced.
(FR)
L'invention concerne un système radar et un procédé ayant des effets réduits de trajets multiples et qui comprennent un premier composant d'un module de capteur radar sur lequel est formé au moins un élément d'antenne, le ou les éléments d'antenne ayant une surface au niveau de laquelle est reçu ou émis un rayonnement radar, le ou les éléments d'antenne ayant une ouverture de rayonnement. Un second composant à proximité de l'élément d'antenne de telle sorte qu'une partie du rayonnement radar vienne frapper le second composant comprend une surface inclinée formant un angle avec la surface de l'élément d'antenne. La surface inclinée du second composant comprend une texture telle que lorsque la partie du rayonnement vient frapper la surface inclinée, la quantité de signal à trajets multiples se propageant à travers l'ouverture de rayonnement de l'élément d'antenne est réduite.
