Abstract:
(EN) [Problem] To provide a radar device that can accurately acquire a delay time from when a detection signal arrives at a transponder until when said transponder transmits a response signal. [Solution] This radar device comprises a response signal detection unit, a transponder reflected wave detection unit, and a response delay acquiring unit. The response signal detection unit detects, from a reception signal generated as a result of reception of a reflected wave of a detection signal transmitted from an antenna, a response signal transmitted by a transponder in response to the detection signal. The transponder reflected wave detection unit detects a reflected wave that appears at an earlier timing than the response signal in the reception signal as the reflected wave of the transponder. The response delay acquiring unit acquires the response delay of the transponder on the basis of the time difference between the reflected wave and the response signal.
(FR) Le problème décrit par la présente invention est de fournir un dispositif radar permettant d'acquérir avec précision un temps de retard depuis le moment où un signal de détection arrive au niveau d'un transpondeur jusqu'à ce que ledit transpondeur émette un signal de réponse. La solution de l'invention porte sur un dispositif radar comprenant une unité de détection de signal de réponse, une unité de détection d'onde réfléchie de transpondeur et une unité d'acquisition de retard de réponse. L'unité de détection de signal de réponse détecte, à partir d'un signal de réception généré suite à la réception d'une onde réfléchie d'un signal de détection émis par une antenne, un signal de réponse émis par un transpondeur en réponse au signal de détection. L'unité de détection d'onde réfléchie de transpondeur détecte une onde réfléchie qui apparaît à un instant antérieur au signal de réponse dans le signal de réception en tant qu'onde réfléchie du transpondeur. L'unité d'acquisition de retard de réponse acquiert le retard de réponse du transpondeur en fonction de la différence de temps entre l'onde réfléchie et le signal de réponse.
(JA) 【課題】探知信号がトランスポンダに到達してから当該トランスポンダが応答信号を送信するまでの遅延時間を正確に取得できるレーダ装置を提供する。 【解 決手段】レーダ装置は、応答信号検出部と、トランスポンダ反射波検出部と、応答遅延取得部と、を備える。前記応答信号検出部は、アンテナから送信した探知 信号の反射波を受信した受信信号から、前記探知信号に反応してトランスポンダが送信する応答信号を検出する。前記トランスポンダ反射波検出部は、前記受信 信号において前記応答信号より早いタイミングで現れる反射波を前記トランスポンダの反射波として検出する。前記応答遅延取得部は、前記反射波と前記応答信 号との時間差に基づいて前記トランスポンダの応答遅延を取得する。
