Abstract:
(EN) To reduce performance degradation in object detection resulting from variation in the characteristics of the elements of a wave transmitter and wave receiver, this transmission device 10 is provided with a transmission signal generator 12 for generating a transmission signal, a wave transmitter 11 that has a plurality of elements and is for transmitting radio waves or sound waves having a desired beam angle, a beam former 13 for adjusting the phase of the transmission signal to be supplied to the wave transmitter 11 for the purpose of changing the beam angle of the radio waves or sound waves, and a correction unit 14 for correcting the amplitude and phase of the transmission signal to be supplied to the wave transmitter 11 according to the beam angle.
(FR) L'invention concerne un dispositif de transmission (10), lequel, afin de réduire la dégradation de la performance dans la détection d'un objet résultant de la variation des caractéristiques des éléments d'un transmetteur d'ondes et d'un récepteur d'ondes, comporte un générateur de signal de transmission (12) pour générer un signal de transmission, un transmetteur d'ondes (11) qui comporte une pluralité d'éléments et qui est destiné à transmettre des ondes radio ou des ondes sonores ayant un angle de faisceau souhaité, un dispositif de formation de faisceau (13) pour régler la phase du signal de transmission à fournir au transmetteur d'ondes (11) pour modifier l'angle de faisceau des ondes radio ou des ondes sonores, et une unité de correction (14) pour corriger l'amplitude et la phase du signal de transmission à fournir au transmetteur d'ondes (11) selon l'angle de faisceau.
(JA) 送波部及び受波部の各素子の特性のバラツキによる対象物の探知性能の低下を軽減するため、送信装置10は、送信信号を生成する送信信号生成部12と、複数の素子を有し、所望ビーム角度の電波又は音波を送信する送波部11と、電波又は音波のビーム角度を変更するため、送波部11に供給される送信信号の位相を調整するビームフォーマー13と、ビーム角度に応じて送波部11に供給される送信信号の振幅と位相を補正する補正部14と、を備えている。
