Title (EN) RADAR DEVICE AND AUTOMOBILE PROVIDED WITH SAME

Abstract:
(EN) Provided is a radar device and an automobile provided with the same, with which it is possible for an angle of elevation or depression of a target object to be measured accurately and inexpensively using a simple circuit, without using a detecting circuit or an AD conversion circuit having high time resolution. A transmission signal wave Stx modulated by means of multilevel FSK is transmitted from a transmission antenna Tx, and a reflected wave that is reflected back by a target object 7 is received by reception antennas Rx(1), ..., Rx(n-1), Rx(n) as a received signal wave Srx. By employing multilevel FSK as the modulation scheme, a beat frequency between the received signal wave Srx from the target object 7 and the transmission signal wave Stx is the Doppler frequency of the target object 7. Therefore, the angle of elevation or depression φ of the target object 7 is calculated by a calculator 6 from the frequency fi of the transmission signal wave Stx, and not from the frequency of the received signal wave as in the past.
(FR) L'invention concerne un dispositif radar et une automobile comprenant de dernier, grâce auquel il est possible qu'un angle d'élévation ou de dépression d'un objet cible soit mesuré de manière précise et peu coûteuse à l'aide d'un circuit simple, sans utiliser un circuit de détection ou un circuit de conversion analogique-numérique présentant une résolution temporelle élevée. Une onde de signal de transmission Stx modulée au moyen d'une FSK multiniveau est émise à partir d'une antenne de transmission Tx, et une onde réfléchie qui est réfléchie par un objet cible (7) est reçue par des antennes de réception Rx(1), ..., Rx(n-1), Rx(n) en tant qu'onde de signal reçu Srx. Par l'utilisation de la FSK multiniveau en tant que schéma de modulation, une fréquence de battement entre l'onde de signal reçu Srx en provenance de l'objet cible (7) et l'onde de signal de transmission Stx constitue la fréquence Doppler de l'objet cible (7). Ainsi, l'angle d'élévation ou de dépression φ de l'objet cible (7) est calculé par un calculateur (6) à partir de la fréquence fi de l'onde de signal de transmission Stx, et non à partir de la fréquence de l'onde de signal reçu comme dans le passé.
(JA) 時間分解能の高い検知回路やAD変換回路を使うことなく、簡単な回路で安価に目標物の仰俯角を精度良く測定できるレーダ装置、およびそれを備える自動車を提供する。多値のFSKによって変調した送信信号波Stxが送信アンテナTxから送信され、目標物7で反射して戻る反射波が受信信号波Srxとして受信アンテナRx(1),…,Rx(n-1),Rx(n)に受信される。変調方式として多値FSKを用いることにより、目標物7からの受信信号波Srxと送信信号波Stxとのビート周波数は目標物7のドップラー周波数となる。したがって、目標物7の仰俯角φは、従来の受信信号波の周波数ではなく、送信信号波Stxの周波数fから、演算器6によって演算される。
