Title (EN) A RADAR SYSTEM COMPRISING AT LEAST TWO SPATIALLY SEPARATED ANTENNA UNITS
(FR) système radar comprenant au moins deux unités d'antenne spatialement distinctes
Abstract: front page image
(EN)A radar system (1), comprising at least two spatially separated antenna units (U1, U2, U3, U4, U5, U6, U7, U8, U9; U1O, U11, U12, U13, U14, U15, U16, U17, U18), each comprising one antenna (2, 3, 4, 5, 6, 7, 8, 9, 21; 36, 37, 38, 39, 40, 41, 42, 43, 56). Each antenna unit (U1, U2, U3, U4, U5, U6, U7, U8, U9; U1 O, U11, U12, U13, U14, U15, U16, U17, U18) comprising a signal generator (13, 14, 15, 16, 17, 18, 19, 20; 57) connected to an antenna (2, 3, 4, 5, 6, 7, 8, 9; 56) constitutes a transmitting antenna unit (U1, U2, U3, U4, U5, U6, U7, U8; U18), and each antenna unit (U9; U10. U11, U12, U13, U14, U15, U16, U17) comprising a receiver (22; 47, 48, 49, 3 50, 51, 52, 53, 54) connected to an antenna (21; 36, 37, 38, 39, 40, 41, 42, 43) constitutes a receiving antenna unit (U9; U10, U11, U12, U13, U14, U15, U16, U17). At least one receiving antenna unit (U9; U10, U11, U12, U13, U14, U15, U16, U17) is arranged for receiving at least one reflected signal, comprising signals transmitted from at least one transmitting antenna unit (U1, U2, U3, U4, U5, U6, U7, U8; U18), having been reflected from at least one object (24), where the number of antenna units (U1, U2, U3, U4, U5, U6, U7, U8, U9; U10, U11, U12, U13, U14, U15, U16, U17, U18) exceeds two. A processing unit (23) is arranged to perform a correlation calculation, comparing at least one received signal with a set of mathematically manipulated copies. From said set, there is only one match for each reflected signal. The present invention also relates to corresponding methods.
(FR)L'invention concerne un système radar (1), comprenant au moins deux unités d'antenne spatialement distinctes (U1, U2, U3, U4, U5, U6, U7, U8, U9; U1O, U11, U12, U13, U14, U15, U16, U17, U18), comprenant chacune une antenne (2, 3, 4, 5, 6, 7, 8, 9, 21; 36, 37, 38, 39, 40, 41, 42, 43, 56). Chaque unité d'antenne (U1, U2, U3, U4, U5, U6, U7, U8, U9; U1 O, U11, U12, U13, U14, U15, U16, U17, U18) comprenant un générateur de signal (13, 14, 15, 16, 17, 18, 19, 20; 57) connecté à une antenne (2, 3, 4, 5, 6, 7, 8, 9; 56) constitue une unité d'antenne d'émission (U1, U2, U3, U4, U5, U6, U7, U8; U18), et chaque unité d'antenne (U9; U10. U11, U12, U13, U14, U15, U16, U17) comprenant un récepteur (22; 47, 48, 49, 3 50, 51, 52, 53, 54) connecté à une antenne (21; 36, 37, 38, 39, 40, 41, 42, 43) constitue une unité d'antenne de réception (U9; U10, U11, U12, U13, U14, U15, U16, U17). Au moins une unité d'antenne de réception (U9; U10, U11, U12, U13, U14, U15, U16, U17) est agencée pour recevoir au moins un signal réfléchi, comprenant des signaux émis depuis au moins une unité d'antenne d'émission (U1, U2, U3, U4, U5, U6, U7, U8; U18), ayant été réfléchis depuis au moins un objet (24), où le nombre d'unités d'antenne (U1, U2, U3, U4, U5, U6, U7, U8, U9; U10, U11, U12, U13, U14, U15, U16, U17, U18) dépasse deux. Une unité de traitement (23) est agencée pour réaliser un calcul de corrélation, par la comparaison d'au moins un signal reçu avec un jeu de copies mathématiquement manipulées. À partir dudit jeu, il existe seulement une correspondance pour chaque signal réfléchi. La présente invention concerne également des procédés correspondants.
