Abstract
(EN)
A radar sensing system for a vehicle, the radar sensing system including a transmitter and a receiver. The transmitter is configured to transmit a radio signal. The receiver is configured to receive the transmitted radio signal reflected from objects in the environment. The transmitter includes an antenna and is configured to transmit the radio signal via the antenna. The antenna includes a plurality of linear arrays of patch radiators. An arrangement of the linear arrays of patch radiators is selected to form a desired shaped antenna pattern having a desired mainlobe shape and desired shoulder shapes to cover selected sensing zones without nulls or holes in the coverage.

L'invention porte sur un système de détection radar pour un véhicule, le système de détection radar comprenant un émetteur et un récepteur. L'émetteur est configuré de sorte à transmettre un signal radio. Le récepteur est configuré de sorte à recevoir le signal radio émis réfléchi par des objets dans l'environnement. L'émetteur comprend une antenne et est configuré de sorte à transmettre le signal radio par le biais de l'antenne. L'antenne comprend une pluralité de réseaux linéaires d'éléments rayonnants à plaque. Un agencement des réseaux linéaires d'éléments rayonnants à plaque est sélectionné pour former un diagramme d'antenne de forme désirée ayant une forme de lobe principal désirée et des formes d'épaulement souhaitées pour couvrir des zones de détection sélectionnées sans vides ou trous dans la couverture.
