Abstract: Provided is an electronic device configured to transmit, as a transmission wave, a radio wave whose frequency changes over time from a plurality of transmitting antennas. The electronic device includes a phase controller. The phase controller controls a phase of at least one of transmission waves transmitted from a plurality of transmitting antennas so that the phases of respective transmission waves transmitted from the transmitting antennas are aligned in a predetermined direction. Further, the phase controller adjusts the phase of at least one of transmission waves on the basis of a frequency of the transmission wave.

Abstract: An object tracking device that can track an object accurately and consistently is provided. An object tracking device (20) includes an input interface (21), a processor (23), and an output interface (24). The input interface (21) is configured to acquire sensor data. The processor (23) is configured to detect a detection target from the sensor data and track the detection target using Kalman filters associated with each of the detection target and an observed value. The output interface (24) is configured to output a detection result regarding the detection target. The processor (23) is configured to impose a limit on a range of variation in an index of the Kalman filters that influences tracking of the detection target.

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 controller classifies a predetermined target, based on a probability density distribution calculated from a relative velocity of the object relative to the electronic device.

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 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 controller detects an object by using the constant false alarm rate, based on a signal intensity of a complex signal corresponding to a distance of an object whose relative velocity with respect to the electronic device is zero.

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 that 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 sets a test region and at least one or more reference regions with respect to the test region in a distribution of signal intensities based on the reception signal in a distance direction, and sets a threshold for use in detection of the target, based on an order statistic among signal intensities in the reference regions.
