Zusammenfassung:To provide a radar device with which it is possible to detect an observation object more reliably in a short time using the time-series information of electric signals relating to reflected waves corresponding to a phase pattern.SOLUTION: This radar device 1 comprises a plurality of antennas 4 capable of mutually converting radio waves and electric signals and a controller 2, the controller 2 being capable of executing: a process of at least one or more antennas 4 transmitting a radio wave; a process of at least one or more antennas 4 out of the plurality of antennas 4 converting a reflected wave generated by the radio wave as it enters an observation object O to an electric signal, respectively; a process of controlling the phase of each of the electric signals on the basis of a prescribed phase pattern; a process of acquiring a digital signal generated on the basis of a synthesized signal having been synthesized from each of phase-controlled electric signals; and a process of detecting the observation object O using the prescribed phase pattern, the time-series information of digital signal and a prescribed neural network.SELECTED DRAWING: Figure 1 【課題】位相パターンに応じた反射波に関する電気信号の時系列情報を用い、観測対象を短い時間でより確実に探知可能なレーダ装置を提供する。【解決手段】本発明のレーダ装置1は、電波と電気信号とを互いに変換可能な複数のアンテナ4と、コントローラ2と、を備え、コントローラ2は、少なくとも1以上のアンテナ4が電波を送信する処理と、電波が観測対象Oに入射することによって生じた反射波を複数のアンテナ4のうち少なくとも1以上のアンテナ4が電気信号にそれぞれ変換する処理と、所定の位相パターンに基づいて電気信号それぞれの位相を制御する処理と、位相が制御された電気信号それぞれが合成された合成信号に基づいて生成されたデジタル信号を取得する処理と、所定の位相パターン、デジタル信号の時系列情報、及び所定のニューラルネットワークを用いて観測対象Oを探知する処理と、を実行可能である。【選択図】図1
