Abstract:
(EN) [Problem] To provide a TDMA FMCW MIMO radar device that is capable of compensating for Doppler phase shifting of a moving target and improving the accuracy of estimating orientation. [Solution] Provided is a radar device that: switches in sequence so that the numbers of antenna elements have front-rear symmetry about a reference time, and carries out transmission from a transmission antenna; and synthesizes a beat signal at the reference time from a first beat signal received by a reception antenna at or before the reference time and a second beat signal received at or after the reference time.
(FR) Le problème décrit par la présente invention est de fournir un dispositif radar TDMA FMCW MIMO qui peut compenser le décalage de phase Doppler d'une cible mobile et qui peut améliorer la précision de l'estimation d'une orientation. La solution selon l'invention porte sur un dispositif radar qui : commute en séquence de sorte que les nombres d'éléments d'antenne aient une symétrie avant-arrière autour d'un temps de référence, et effectue une émission à partir d'une antenne d'émission ; et synthétise un signal de battement au temps de référence à partir d'un premier signal de battement reçu par une antenne de réception au temps de référence ou avant le temps de référence et d'un second signal de battement reçu au temps de référence ou après le temps de référence.
(JA) 【課題】TDMA FMCW MIMOレーダ装置において、移動物標のドップラ位相シフトを補償して方位推定精度を向上することが可能なことが可能なレーダ装置を提供する。 【解決手段】基準時刻を中心としてアンテナ素子の番号が前後対称となるように順次切り替えて送信アンテナから送信を行い、基準時刻以前に受信アンテナが受信した第1のビート信号と、基準時刻以降に受信した第2のビート信号とから、基準時刻におけるビート信号を合成する、レーダ装置が提供される。
