Title (EN) RADAR DEVICE
(FR) DISPOSITIF RADAR
(JA) レーダー装置
Abstract:
(EN) Provided is a radar device that can acquire three-dimensional information while mitigating an increase in the complexity and size of the device structure. A radar device 100 comprises: an antenna 110 having frequency characteristics in which the emission angle of the elevation angle direction changes according to the supplied frequency; a transmission signal formation unit (control/processing unit 101, oscillator 102, amplifier 103) that supplies a chirp signal to the antenna 110; and a reception processing unit (control/processing unit 101) that acquires a detection point for each frequency band using a reception signal for a transmission signal of each frequency band included in the chirp signal, and that acquires information regarding the height direction on the basis of the presence or absence of the detection points across a plurality of frequency bands.
(FR) Cette invention concerne un dispositif radar qui peut acquérir des informations tridimensionnelles tout en atténuant une augmentation de la complexité et de la taille de la structure du dispositif. Un dispositif radar (100) selon l'invention comprend : une antenne (110) ayant des caractéristiques de fréquence dans lesquelles l'angle d'émission de la direction d'angle d'élévation change en fonction de la fréquence fournie ; une unité de formation de signal de transmission (unité de commande/traitement (101), oscillateur (102), amplificateur (103)) qui fournit un signal de compression d'impulsion à l'antenne (110) ; et une unité de traitement de réception (unité de commande/traitement (101)) qui acquiert un point de détection pour chaque bande de fréquences à l'aide d'un signal de réception pour un signal de transmission de chaque bande de fréquences incluse dans le signal de compression d'impulsion, et qui acquiert des informations concernant la direction de hauteur sur la base de la présence ou de l'absence des points de détection sur une pluralité de bandes de fréquences.
(JA) 装置構成が複雑化及び大型化することを抑制しつつ、3次元の情報を取得可能なレーダー装置。レーダー装置100は、供給される周波数に応じて仰角方向の放射角が変化する周波数特性を有するアンテナ110と、アンテナ110にチャープ信号を供給する送信信号形成部(制御・処理部101、発振器102、アンプ103)と、チャープ信号に含まれる各周波数帯域の送信信号についての受信信号を用いて各周波数帯域の検出点を得、複数の周波数帯域に亘る検出点の存在の有無に基づいて高さ方向の情報を得る受信処理部(制御・処理部101)と、を有する。
