Abstract: An electronic device includes a transmission antenna, a reception antenna, 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 controller detects an object that reflects the transmission wave, based on a transmission signal transmitted as the transmission wave and a reception signal received as the reflected wave. The electronic device determines a parameter to be used in determination as to whether the object is detected, based on a height of the electronic device.

Abstract: An electronic device includes a transmission antenna, a reception antenna, a cover part, and a signal processor. The transmission antenna is configured to transmit a transmission wave. The reception antenna is configured to receive a reflection wave resulting from reflection of the transmission wave. The cover part is configured to cover at least part of at least one of the transmission antenna or the reception antenna. The signal processor is configured to detect an object that reflects the transmission wave based on at least one of a transmission signal transmitted as the transmission wave or a reception signal received as the reflection wave. At least part of at least one of the transmission wave transmitted by the transmission antenna or the reflection wave received by the reception antenna is transmitted and/or received via the cover part. A thickness of the cover part is designed based on magnitude-squared coherence.

Abstract: An electronic device includes transmission antennas, reception antennas, and an electronic component. The transmission antennas each transmit a transmission wave. The reception antennas each receive a reflected wave that is the transmission wave having been reflected. The electronic component outputs respective transmission signals to the transmission antennas and receive respective reception signals from the reception antennas. The electronic component has a first edge where transmission terminals that output the respective transmission signals to the transmission antennas are arranged, and a second edge where reception terminals that receive the respective reception signals from the reception antennas are arranged. At least one of the first edge or the second edge is located obliquely relative to at least one of a direction in which respective feeding points of the transmission antennas are arranged or a direction in which respective feeding points of the reception antennas are arranged.

Abstract: An electronic device includes a transmission antenna that transmits a transmission wave, a reception antenna that receives a reflected wave that is the transmission wave having been reflected, and a control unit. The control unit detects 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. The control unit establishes reference regions non-contiguously in a distance direction and a relative velocity direction with respect to a test region in a two-dimensional distribution of signal intensities based on the reception signal in the distance direction and the relative velocity direction. The control unit sets a threshold for use in detection of the target, based on an order statistic among the signal intensities in the reference regions.
