Abstract
(EN)
The present disclosure provides a system for processing radar data. The system may comprise a frequency generator configured to generate a reference frequency signal; a timing module configured to generate one or more timing signals; and a plurality of radar modules in communication with the frequency generator and timing module. The radar modules may be configured to: (i) receive the reference frequency signal and the one or more timing signals, (ii) transmit a first set of radar signals based in part on the reference frequency signal and the one or more timing signals, and (iii) receive a second set of radar signals reflected from a surrounding environment. The system may comprise a processor configured to process radar signals received by the plurality of radar modules, by coherently combining radar signals using phase and timestamp information.

La présente invention concerne un système de traitement de données radar. Le système peut comprendre un générateur de fréquence configuré pour générer un signal de fréquence de référence ; un module de synchronisation configuré pour générer un ou plusieurs signaux de synchronisation ; et une pluralité de modules de radar en communication avec le générateur de fréquence et le module de synchronisation. Les modules radar peuvent être configurés pour : (I) recevoir le signal de fréquence de référence et lesdits signaux de synchronisation, (ii) émettre un premier ensemble de signaux radar en fonction en partie du signal de fréquence de référence et desdits signaux de synchronisation, et (iii) recevoir un second ensemble de signaux radar réfléchis par un environnement ambiant. Le système peut comprendre un processeur configuré pour traiter des signaux radar reçus par la pluralité de modules radar, par combinaison cohérente de signaux radar à l'aide d'informations de phase et d'horodatage.
