Abstract
(EN)
A dielectric lens device (14; 40) for shaping a radar beam comprises a first (16; 42) and a second plano-convex cylindrical dielectric lens member (20; 52), and a plane-parallel dielectric substrate (24). The two plano-convex cylindrical dielectric lens members (16, 20; 42, 52) are arranged with their plane surfaces towards a same surface of the plane-parallel dielectric substrate (24). The plano-convex cylindrical dielectric lens members (16, 20; 42, 52) are interconnected to the plane-parallel dielectric substrate (24) in a material fit.

La présente invention concerne un dispositif de lentille diélectrique (14 ; 40) pour mettre en forme un faisceau radar comprenant un premier (16 ; 42) élément de lentille diélectrique cylindrique plan-convexe et un second élément de lentille diélectrique cylindrique plan-convexe (20 ; 52), et un substrat diélectrique plan-parallèle (24). Les deux éléments de lentille diélectrique cylindrique plan-convexe (16, 20 ; 42, 52) sont agencés avec leurs surfaces planes vers une même surface du substrat diélectrique plan-parallèle (24). Les éléments de lentille diélectrique cylindrique plan-convexe (16, 20 ; 42, 52) sont interconnectés au substrat diélectrique plan-parallèle (24) dans un ajustement de matériau.
