A driving assistance apparatus according to the present invention may comprise: a radar which is provided on a vehicle, has a detection field of view toward the outside of the vehicle, and provides object data; and a control unit that recognizes a distance from the vehicle to an object in the vicinity of the vehicle and a moving speed of the object on the basis of a processing result of the object data. The radar may include: a plurality of transmit antennas; a plurality of receiving antennas; and a signal processor that provides the transmission signals to the plurality of transmission antennas such that the plurality of transmission antennas transmit the plurality of transmission radio waves, the signal processor obtaining the plurality of reception signals received by the plurality of reception antennas. The signal processor may perform a two-dimensional fast Fourier transform on each of the plurality of received signals, and may determine an angle of the object based on a position of the object; a phase corresponding to an angle of the object may be subtracted from the plurality of received signals, and a phase difference between the plurality of transmitted radio waves may be identified based on the plurality of received signals from which the phase is subtracted.

    根据本发明的驾驶辅助装置,其可以包括:雷达,其设置在车辆上并具有朝向所述车辆外部的探测视野,并用于提供对象数据;以及控制部,其基于针对对象数据的处理结果来识别车辆至车辆周边的对象的距离以及对象的移动速度。雷达可以包括:多个发送天线;多个接收天线;以及信号处理器,其向多个发送天线提供传输信号,使得多个发送天线发射多个传输电波,信号处理器获得由多个接收天线接收的多个接收信号。信号处理器可以对多个接收信号的每一个接收信号执行二维快速傅里叶变换,并可以基于对象的位置判断对象的角度;可以从多个接收信号中减去与对象的角度相对应的相位,并可以基于减去相位的多个接收信号而识别多个传输电波之间的相位差。
