Title
(EN) TIME-FREQUENCY SPREAD WAVEFORM FOR HIGH-RESOLUTION DIGITAL RADAR
(FR) FORME D'ONDE À ÉTALEMENT TEMPS-FRÉQUENCE POUR RADAR NUMÉRIQUE À HAUTE RÉSOLUTION
Abstract
(EN)
The apparatus (1500) includes: a radar circuit (1502) including a set of antennas for transmission (205) and reception (305), a transmitter (600), a receiver (800), and a medium access control (MAC) controller (1522). The apparatus (1500) further includes a controller (1520) operably connected to the radar circuit (1502), the controller (1520) configured to identify a discrete Fourier transform (DFT) of a long constant amplitude zero autocorrelation (CAZAC) sequence including multiple segments, identify, via the MAC controller (1522), time-frequency resources for the multiple segments, identify a set of time-frequency sub-channels in the time-frequency resources, and sequentially map each of the multiple segments to each of the set of time-frequency sub-channels. The radar circuit (1502) is configured to transmit, via the transmitter (600), a first signal based on the set of time-frequency sub-channels.

L'appareil (1500) comprend : un circuit radar (1502) comprenant un ensemble d'antennes pour la transmission (205) et la réception (305), un émetteur (600), un récepteur (800), et un dispositif de commande de commande d'accès au support (MAC) (1522). L'appareil (1500) comprend en outre un dispositif de commande (1520) connecté de manière fonctionnelle au circuit radar (1502), le dispositif de commande (1520) configuré pour identifier une transformée de Fourier discrète (DFT) d'une séquence d'amplitude constante et d'autocorrélation nulle (CAZAC) longue comprenant de multiples segments, identifier, par l'intermédiaire du dispositif de commande MAC (1522), des ressources temps-fréquence pour les multiples segments, identifier un ensemble de sous-canaux temps-fréquence dans les ressources temps-fréquence, et mapper séquentiellement chacun des multiples segments à chacun de l'ensemble de sous-canaux temps-fréquence. Le circuit radar (1502) est configuré pour transmettre, par l'intermédiaire de l'émetteur (600), un premier signal sur la base de l'ensemble de sous-canaux temps-fréquence.
