Title (EN) RADAR DEVICE
(FR) DISPOSITIF RADAR
(JA) レーダ装置
Abstract:
(EN) To accurately detect interference in a radar device, this radar apparatus 1 is provided with: an average amplitude calculation unit 122 that calculates an average amplitude of a beat signal based on a transmission signal and a reception signal; and an interference detection unit 123 that detects an interference signal with respect to the reception signal on the basis of the average amplitude of the beat signal calculated by the average amplitude calculation unit 122.
(FR) Selon la présente invention, afin de détecter avec précision des interférences dans un dispositif radar, cet appareil radar (1) comporte : une unité de calcul d'amplitude moyenne (122) qui calcule l'amplitude moyenne d'un signal de battement sur la base d'un signal de transmission et d'un signal de réception ; et une unité de détection d'interférence (123) qui détecte un signal d'interférence par rapport au signal de réception sur la base de l'amplitude moyenne du signal de battement calculé par l'unité de calcul d'amplitude moyenne (122).
(JA) レーダ装置における干渉検出を正確に行う。レーダ装置1は、送信信号と受信信号とに基づくビート信号の平均振幅を算出する平均振幅算出部122と、平均振幅算出部122により算出されたビート信号の平均振幅に基づいて受信信号に対する干渉信号を検出する干渉検出部123と、を備える。
