(EN) An electronic device comprises a transmission antenna that transmits transmission waves, a reception antenna that receives reflection waves to which the transmission waves are reflected, and a control unit. The control unit detects a target with a certain false-alarm probability, on the basis of transmission signals transmitted as transmission waves and reception signals received as reflection waves. The control unit provides, in a distance direction distribution of signal strength based on reception signals, a reference region at a far side in the distance direction with an inspection region as a reference, and sets a threshold value used for detecting the target on the basis of order statistics of the signal strength in the reference region.
(ZH) 电子设备具有:发送天线,发送发送波;接收天线,接收发送波被反射后的反射波;以及控制部。控制部基于作为发送波而被发送的发送信号以及作为反射波而被接收的接收信号,利用恒定虚警率检测目标。控制部在基于接收信号的信号强度的距离方向的分布中,以检查区域为基准在距离方向的远处设置参照区域,基于参照区域中的信号强度的顺序统计量来设定在目标的检测中使用的阈值。
