Abstract
An electronic device includes a transmission antenna, a reception antenna, a signal processor, a quality determining unit, and a controller. The transmission antenna transmits a transmission wave. The reception antenna receives a reflected wave that is the transmission wave having been reflected. The signal processor calculates, based on a transmission signal transmitted as the transmission wave and a reception signal received as the reflected wave, a distance between the electronic device and an object that reflects the transmission wave. The quality determining unit determines a quality of the reception signal. The controller performs control for transmitting the transmission wave in an operation mode corresponding to the distance between the electronic device and the object, based on the quality of the reception signal determined by the quality determining unit.
