Title (EN) LOW POWER MODE OF OPERATION FOR MM-WAVE RADAR
(FR) MODE DE FONCTIONNEMENT À FAIBLE PUISSANCE POUR RADAR À ONDES MILLIMÉTRIQUES
Abstract:
(EN) Described examples include a radar system that operates in a first mode (201) and a second mode (210). In the first mode (201), the system detects the presence of an object within a threshold range. In response to detection of the presence of the object, the system transitions to the second mode (210), and the system generates range data (216), velocity data (218) and angle data (220) of the object in the second mode (210). When the object is no longer detected within the threshold range, the system transitions back to the first mode (201).
(FR) La présente invention décrit des exemples comprenant un système radar qui fonctionne dans un premier mode (201) et un second mode (210). Dans le premier mode (201), le système détecte la présence d'un objet dans une portée seuil. En réponse à la détection de la présence de l'objet, le système passe au second mode (210), et le système génère des données de portée (216), des données de vitesse (218) et des données d'angle (220) de l'objet dans le second mode (210). Lorsque l'objet n'est plus détecté dans la portée seuil, le système passe revient au premier mode (201).
