Abstract:
(EN) According to the present invention, a range-direction frequency domain conversion unit (231-1) converts a received video signal into a signal based on a range-direction frequency. A hit-direction frequency domain conversion unit (232-1) converts the signal based on the range-direction frequency into a signal based on the speed and the range-direction frequency so that an intended Doppler frequency belongs to the same speed bin number independently of a change in the frequency of a transmitted signal. A correlation unit (233-1) generates a signal based on post-correlation distance and speed separated for each transmission frequency. An integration unit (234-1) generates a signal based on post-correlation distance and speed obtained through frequency band synthesis. A target candidate detection unit (241) detects, in signals outputted from the integration unit (233-1), a target candidate on the basis of the signal intensity. A target relative speed/relative distance/arrival angle calculation unit (242) calculates the relative speed, the relative distance, and the arrival angle for the target candidate.
(FR) Selon la présente invention, une unité de conversion de domaine de fréquence de distance-direction (231-1) convertit un signal vidéo reçu en un signal basé sur une fréquence distance-direction. Une unité de conversion de domaine de fréquence cible-direction (232-1) convertit le signal basé sur la fréquence distance-direction en signal basé sur la vitesse et la fréquence distance-direction de sorte qu'une fréquence Doppler souhaitée appartienne au même numéro de case de vitesse indépendamment d'un changement de la fréquence d'un signal émis. Une unité de corrélation (233-1) génère un signal basé sur une distance et d'une vitesse post-corrélation séparées pour chaque fréquence d'émission. Une unité d'intégration (234-1) génère un signal basé sur une distance et une vitesse post-corrélation obtenues par synthèse de bande de fréquence. Une unité de détection de candidat cible (241) détecte, dans les signaux délivrés en sortie par l'unité d'intégration (233-1), un candidat cible sur la base de l'intensité de signal. Une unité de calcul d'angle de vitesse relative/distance relative/angle d'arrivée cible (242) calcule la vitesse relative, la distance relative et l'angle d'arrivée pour le candidat cible.
(JA) 距離方向周波数領域変換部(231-1)は、受信ビデオ信号を距離方向周波数に基づく信号に変換する。ヒット方向周波数領域変換部(232-1)は、距離方向周波数に基づく信号を、送信信号の周波数の変化とは独立して目標のドップラ周波数が同一の速度ビン番号に属するように、速度と距離方向周波数に基づく信号に変換する。相関部(233-1)は、送信周波数毎に分離された速度と相関後の距離に基づく信号を生成する。積分部(234-1)は、帯域合成された速度と相関後の距離に基づく信号を生成する。目標候補検出部(241)は、積分部(233-1)の出力信号に対して、信号強度に基づき目標候補を検出する。目標相対速度・相対距離・到来角算出部(242)は、目標候補の相対速度、相対距離及び到来角を算出する。
