Abstract: An electronic device comprises: a transmission antenna configured to transmit transmission waves; a reception antenna configured to receive reflected waves resulting from reflection of the transmission waves; and a controller. The controller is configured to detect an object reflecting the transmission waves, based on a transmission signal transmitted as the transmission waves and a reception signal received as the reflected waves. The controller is configured to make a range of detection of the object by the transmission signal and the reception signal, variable.

Abstract: An electronic device 1 comprises: a transmitting antenna configured to transmit transmitted waves; a receiving antenna configured to receive reflected waves obtained by reflection of the transmitted waves; and a controller. The controller detects, based on transmitted signals transmitted as the transmitted waves and received signals received as the reflected waves, an object reflecting the transmitted waves. The controller determines frequencies of transmitted waves to be transmitted from the transmitting antenna based on results of receiving, from the receiving antenna, each of reflected waves obtained by reflection of a plurality of transmitted waves with different frequencies transmitted from the transmitting antenna.
