Title (EN) METHOD AND SYSTEM FOR OBTAINING AN ADAPTIVE ANGLE-DOPPLER AMBIGUITY FUNCTION IN MIMO RADARS
(FR) PROCÉDÉ ET SYSTÈME D'OBTENTION D'UNE FONCTION D'AMBIGUÏTÉ D'ANGLE DOPPLER ADAPTATIVE DANS DES RADARS MIMO
Abstract:
(EN) A method for obtaining an adaptive angle-Doppler ambiguity function (AF) for a target using multiple-input-multiple-output (MIMO) radar, the MIMO radar including a transmit antenna array, the transmit antenna array being at least one-dimensional and having a plurality of antenna elements. The method comprises generating transmit signals for transmission by the transmit antenna array, the transmit signals defining at least a first transmit trajectory of a phase center within the transmit antenna array. The method further comprises transmitting the transmit signals using the transmit antenna array and receiving receive signals from the target, the receive signals resulting from the incidence of the transmit signals upon the target. The method further comprises obtaining at least an angle-Doppler ambiguity function (AF) from the receive signals. The method is characterised in that the first transmit trajectory is such that, in operation, the phase center undergoes random phase center motion (PCM), such that a phase center position within the transmit antenna array varies randomly with time. A system for obtaining an AF is also disclosed.
(FR) La présente invention concerne un procédé d'obtention d'une fonction d'ambiguïté (AF) d'angle Doppler adaptative pour une cible à l'aide d'un radar à entrée multiple-sortie multiple (MIMO), le radar MIMO comprenant un réseau d'antennes d'émission, le réseau d'antennes d'émission étant au moins unidimensionnel et ayant une pluralité d'éléments d'antenne. Le procédé consiste à générer des signaux d'émission destinés à être émis par le réseau d'antennes d'émission, les signaux d'émission définissant au moins une première trajectoire d'émission d'un centre de phase à l'intérieur du réseau d'antennes d'émission. Le procédé comprend en outre l'émission des signaux d'émission à l'aide du réseau d'antennes d'émission et la réception de signaux de réception en provenance de la cible, les signaux de réception résultant de l'incidence des signaux d'émission sur la cible. Le procédé comprend en outre l'obtention d'au moins une fonction d'ambiguïté (AF) d'angle Doppler à partir des signaux de réception. Le procédé est caractérisé en ce que la première trajectoire d'émission est telle que, en fonctionnement, le centre de phase subit un mouvement de centre de phase (PCM) aléatoire, de sorte qu'une position de centre de phase dans le réseau d'antennes d'émission varie de manière aléatoire avec le temps. L'invention concerne également un système permettant d'obtenir une AF.
