Abstract
(EN)
Aspects of the present disclosure provide for a radar system including a radar IC (300) including a timing engine (342), a local oscillator (330), and a modulator (350). The timing engine is configured to generate one or more chirp control signals. The local oscillator is configured to receive the one or more chirp control signals and generate a frame including a first sequence of chirps according to the one or more chirp control signals. The modulator is configured to modulate the first sequence of chirps to generate a second sequence of chirps so the frame includes the first sequence of chirps and the second sequence of chirps offset by a first frequency value.

Des aspects de la présente invention concernent un système radar comprenant un circuit intégré de radar (300) comprenant un moteur de synchronisation (342), un oscillateur local (330) et un modulateur (350). Le moteur de synchronisation est configuré pour générer un ou plusieurs signaux de commande de compression d'impulsions. L'oscillateur local est configuré pour recevoir le ou les signaux de commande de compression d'impulsions et générer une trame comprenant une première séquence de compressions d'impulsions selon le ou les signaux de commande de compression d'impulsions. Le modulateur est configuré pour moduler la première séquence de compressions d'impulsions en vue de générer une seconde séquence de compressions d'impulsions de sorte que la trame comprend la première séquence de compressions d'impulsions et la seconde séquence de compressions d'impulsions décalées d'une première valeur de fréquence.
