Abstract
(EN)
This radar device (1) is provided with a transmission unit (2), a receiving antenna unit (4), a receiving unit (5), a frequency analysis unit (S70), a first correlation matrix generation unit (S120) and an averaging processing unit (S130). For each repetition cycle, the transmitting unit transmits a repetition number of chirps. For each receiving antenna and for each beat signal, the frequency analysis unit calculates a distance spectrum. For each of the chirps, the first correlation matrix generation unit generates a first correlation matrix for each long-distance bin on the basis of complex information about long-distance bins in distance spectrums corresponding to each of receiving antennas that received the same chirp. For each long-distance bin, the averaging processing unit generates an average correlation matrix by performing averaging processing of the repetition number of first correlation matrices generated corresponding to the long-distance bins.

Dispositif radar (1) pourvu d'une unité de transmission (2), d'une unité d'antenne de réception (4), d'une unité de réception (5), d'une unité d'analyse de fréquence (S70), d'une première unité de génération de matrice de corrélation (S120) et d'une unité de traitement de moyenne (S130). Pour chaque cycle de répétition, l'unité de transmission transmet un nombre de répétitions de chirps. Pour chaque antenne de réception et pour chaque signal de battement, l'unité d'analyse de fréquence calcule un spectre de distance. Pour chacun des chirps, la première unité de génération de matrice de corrélation génère une première matrice de corrélation pour chaque fichier longue distance sur la base d'informations complexes concernant des fichiers longue distance dans des spectres de distance correspondant à chacune des antennes de réception qui ont reçu le même chirp. Pour chaque fichier longue distance, l'unité de traitement de moyenne génère une matrice de corrélation de moyenne en effectuant un traitement de moyenne du nombre de répétitions de premières matrices de corrélation générées correspondant aux fichiers longue distance.

レーダ装置(1)は、送信部(2)と受信アンテナ部(4)と受信部(5)と周波数解析部(S70)と第1相関行列生成部(S120)と平均化処理部(S130)とを備える。送信部は、チャープを繰返周期毎に繰返数だけ送信する。周波数解析部は、受信アンテナ毎に且つビート信号毎に、距離スペクトラムを算出する。第1相関行列生成部は、チャープのそれぞれについて、同一のチャープを受信した受信アンテナのそれぞれに対応する距離スペクトラムにおける遠距離ビンの複素情報に基づいて、遠距離ビン毎に第1相関行列を生成する。平均化処理部は、遠距離ビン毎に、遠距離ビンに対応して生成された繰返数の第1相関行列の平均化処理を実行することにより、平均相関行列を生成する。
