Title (EN) MULTI-MODE RADAR SYSTEMS, SIGNAL PROCESSING METHODS AND CONFIGURATION METHODS USING PUSHING WINDOWS
(FR) SYSTÈMES RADAR MULTIMODES, PROCÉDÉS DE TRAITEMENT DE SIGNAUX ET PROCÉDÉS DE CONFIGURATION UTILISANT DES FENÊTRES DE POUSSÉE
Abstract:
(EN) A multi-mode radar system (100) uses predetermined range/mode-specific pushing windows (142, 144, 146) to perform windowing on range and velocity object data (162, 164) before performing an FFT on the windowed object data matrix (168) to generate a three-dimensional object matrix including range, velocity and angle data. The individual windows (142, 144, 146) have a combined angular spectral response that corresponds to an angular coverage field of view (FOV) of the transmit and receive antennas (106, 108) for the corresponding mode (LRR, MRR, SRR) to minimize the total weighted energy outside the main lobe and to provide increasing spectral leakage outside the combined angular coverage field of view with angular offset from the main lobe to push out much of the spectral leakage into regions where leakage tolerance is high due to the corresponding combined angular coverage field of view of the transmit and receive antennas (106, 108).
(FR) L'invention concerne un système radar multi-mode (100) utilisant des fenêtres de poussée spécifiques de plage/mode prédéfinies (142, 144, 146) pour effectuer un fenêtrage sur des données d'objet de plage et de vitesse (162, 164) avant d'effectuer une FFT sur la matrice de données d'objet fenêtré (168) pour générer une matrice d'objet en trois dimensions comprenant des données de plage, de vitesse et d'angle. Les fenêtres individuelles (142, 144, 146) ont une réponse spectrale angulaire combinée qui correspond à un champ de vision (FOV) de couverture angulaire des antennes d'émission et de réception (106, 108) pour le mode correspondant (LRR, MRR, SRR) pour réduire au minimum l'énergie totale pondérée à l'extérieur du lobe principal et pour fournir une fuite spectrale croissante à l'extérieur du champ de vision de couverture angulaire combiné avec un décalage angulaire à partir du lobe principal pour sortir la plupart de la fuite spectrale dans des régions où la tolérance aux fuites est élevée en raison du champ de vision de couverture angulaire combiné correspondant des antennes d'émission et de réception (106, 108).
