This electronic device detects an object that reflects a transmission wave on the basis of a transmission signal transmitted as the transmission wave from a transmission antenna and a reception signal received from a reception antenna as a reflected wave of the transmission wave. The electronic device determines that an object has been detected, when a peak in a result obtained by performing a Fourier transform process on a beat signal generated on the basis of the transmission signal and the reception signal is equal to or greater than a predetermined threshold. The electronic device sets the predetermined threshold on the basis of an object detection probability.

    电子设备基于作为发送波从发送天线发送的发送信号以及作为发送波被反射后的反射波从接收天线接收的接收信号,来检测反射发送波的对象物。当对基于发送信号以及接收信号生成的差拍信号进行了傅里叶变换处理而得到的结果中的峰值在规定的阈值以上时,电子设备判定为检测到对象物。电子设备基于物体检测概率设定规定的阈值。
