1. An electronic device comprising:
a transmission antenna configured to transmit a transmission wave;
a reception antenna configured to receive a reflected wave that is the transmission wave having been reflected; and
a controller configured to detect a target by using a constant false alarm rate, based on a transmission signal transmitted as the transmission wave and a reception signal received as the reflected wave, wherein
the controller is configured to detect an object by using the constant false alarm rate, based on a signal intensity of a complex signal corresponding to a distance of the object whose relative velocity with respect to the electronic device is zero,
the controller is configured to detect the object by using the constant false alarm rate, based on a signal intensity stored as the signal intensity of the complex signal corresponding to the distance of the object whose relative velocity with respect to the electronic device is zero, and
the controller is configured to detect the object by using the constant false alarm rate, based on a difference between the signal intensity of the complex signal corresponding to the distance of the object whose relative velocity with respect to the electronic device is zero and the signal intensity stored by the controller.
