Abstract
(EN) A radar device (100) comprises an antenna unit (22) that emits radar waves into a space, a high-frequency circuit (17) that receives, via the antenna unit (22), waves reflected from a target of the radar waves, and a baseband circuit (18) that converts a received signal outputted from the high-frequency circuit (17) into a baseband signal having a digital value. In the antenna unit (22), the high-frequency circuit (17), and the baseband circuit (18), a plurality of reception channels are configured. The baseband circuit (18) includes a baseband amplifier (20) that amplifies, for each of the reception channels, the received signal outputted from the high-frequency circuit and performs parallel addition, and an analog-digital converter (14) that converts an analog signal outputted from the baseband amplifier (20) into a digital value.
(FR) L'invention concerne un dispositif radar (100) comprenant une unité d'antenne (22) émettant des ondes radar dans un espace ; un circuit à hautes fréquences (17) recevant des ondes réfléchies par une cible des ondes radar par l'intermédiaire de l'unité d'antenne (22) ; et un circuit de bande de base (18) convertissant un signal reçu émis par le circuit à hautes fréquences (17) en un signal de bande de base à valeur numérique. Une pluralité de canaux de réception sont conçus dans l'unité d'antenne (22), dans le circuit à hautes fréquences (17) et dans le circuit de bande de base (18). Le circuit de bande de base (18) contient un amplificateur de bande de base (20) qui amplifie, pour chacun des canaux de réception, le signal reçu émis par le circuit à hautes fréquences et qui effectue une addition parallèle ; et un convertisseur analogique-numérique (14), qui convertit un signal analogique émis par l'amplificateur de bande de base (20) en valeur numérique.
