Summary:To provide a radar device, an object detection method and a program, which can analyze information between a plurality of received frames efficiently in a short time.SOLUTION: The radar device comprises: a distance computing unit 22 for calculating distance information to one or a plurality of objects on the basis of a plurality of received signals; a speed computing unit 23 for calculating relative speed information to the one or plurality of objects on the basis of the plurality of received signals; a selection unit 31 for selecting amplitude information, as first amplitude information, that corresponds to a specific physical quantity from among amplitude information corresponding to the distance information or the relative speed information; a first target determination unit 34 for determining a target on the basis of the first amplitude information; and a second target determination unit 25 for determining a target on the basis of second amplitude information. The first target determination unit 34 compounds first amplitude the information obtained at least from a first received signal R1 and a second received signal R2, and determines a target on the basis of the compounded first amplitude information.SELECTED DRAWING: Figure 1 【課題】受信した複数のフレーム間の情報の解析を短い時間で効率的に処理することができるレーダ装置、対象物検出方法およびプログラムを提供する。【解決手段】複数の受信信号に基づいて、１または複数の対象物との距離情報を算出する距離演算部２２と、複数の受信信号に基づいて、１または複数の対象物との相対速度情報を算出する速度演算部２３と、距離情報または相対速度情報に対応する振幅情報の中から特定の物理量に対応する振幅情報を第１振幅情報として選択する選択部３１と、第１振幅情報に基づいて物標の判定を行う第１物標判定部３４と、第２振幅情報に基づいて物標の判定を行う第２物標判定部２５と、備え、第１物標判定部３４は、少なくとも第１受信信号Ｒ１および第２受信信号Ｒ２から得られた第１振幅情報を複合するとともに、当該複合された第１振幅情報に基づいて物標の判定を行う。【選択図】図１
