Abstract: front page image
(EN)A vehicle radar of the present invention comprises: a transmission antenna for emitting a frequency-modulated transmission signal; a plurality of reception antennas detecting the transmission signal reflected from an object so as to respectively output detection signals; a plurality of low-noise amplification units including low-noise amplifiers provided in at least two stages, and low-noise-amplifying the detection signals; and a plurality of frequency-down converters processing the low-noise-amplified detection signals so as to output beat frequency signals, and analyzes the beat frequency signals, thereby detecting the speed of the object, and the distance with and the angle of the object. The transmission antenna and the plurality of reception antennas are formed in a microstrip patch form so as to have a major axis in the vertical direction, the plurality of reception antennas are arranged by being spaced from each other in the horizontal direction, the arrangement of the plurality of reception antennas and the transmission antenna are spaced from each other in the vertical direction, and a ground electrode is interposed in a gap at which the arrangement of the plurality of reception antennas and the transmission antenna are spaced from each other.
(FR)L'invention concerne un radar de véhicule qui comprend : une antenne d'émission permettant d'émettre un signal d'émission modulé en fréquence ; une pluralité d'antennes de réception détectant le signal d'émission réfléchi par un objet de manière à fournir respectivement en sortie des signaux de détection ; une pluralité d'unités d'amplification à faible bruit comprenant des amplificateurs à faible bruit prévus dans au moins deux étages, et amplifiant à faible bruit les signaux de détection ; et une pluralité de convertisseurs abaisseurs de fréquence traitant des signaux de détection amplifiés à faible bruit de manière à délivrer en sortie des signaux de fréquence de battement, et analyse les signaux de fréquence de battement, ce qui permet de détecter la vitesse de l'objet, la distance par rapport à l'objet et l'angle de l'objet. L'antenne d'émission et la pluralité d'antennes de réception ont la forme d'une plaque en microruban de façon à avoir un axe majeur dans la direction verticale, la pluralité d'antennes de réception est agencée selon un espacement dans la direction horizontale, la pluralité d'antennes de réception et l'antenne d'émission sont espacées dans la direction verticale, et une électrode de masse est interposée dans un espace au niveau duquel la pluralité d'antennes de réception et l'antenne d'émission sont espacées.
(KO)본 발명의 차량 레이더는 주파수 변조된 송신 신호를 방사하는 송신 안테나; 물체에 반사된 상기 송신 신호를 검출하여 검출 신호를 각각 출력하는 복수의 수신 안테나; 적어도 2단으로 구성된 저잡음 증폭기를 포함하고, 상기 검출 신호를 저잡음 증폭하는 복수의 저잡음 증폭부; 및 저잡음 증폭된 상기 검출 신호를 처리하여 비트 주파수 신호(beat frequency signal)를 출력하는 복수의 주파수 하향 변환기를 포함하고, 상기 비트 주파수 신호를 분석함으로써 상기 물체의 속도, 상기 물체와의 거리 및 각도를 검출하며, 상기 송신 안테나 및 상기 복수의 수신 안테나는 마이크로스트립 패치(microstrip patch) 형태로 세로 방향의 장축을 갖도록 형성되고, 상기 복수의 수신 안테나는 가로 방향으로 서로 이격되어 배열되고, 상기 복수의 수신 안테나의 배열과 상기 송신 안테나는 세로 방향으로 서로 이격되고, 상기 복수의 수신 안테나의 배열과 상기 송신 안테나가 이격된 간격 사이에 접지 전극이 개재된다.
