Abstract: An electronic device includes a transmission antenna, a plurality of reception antenna arrays, and a signal processor. The transmission antenna transmits a transmission wave. Each of the plurality of reception antenna arrays includes a plurality of reception antennas each configured to receive a reflected wave. The reflected wave is the transmission wave having been reflected. The signal processor detects, based on a transmission signal transmitted as the transmission wave and a reception signal received as the reflected wave, displacement of a subject reflecting the transmission wave. The plurality of reception antenna arrays is arranged in different orientations from one another. The signal processor synthesizes the displacement of the subject detected by each of the plurality of reception antenna arrays.

Abstract: Provided are an object tracking device and an object tracking method that allow multiple objects to be tracked with high accuracy. 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 multiple detection targets from the sensor data and perform tracking using a Kalman filter for each of the multiple detection targets. The output interface (24) is configured to output detection results of the detection targets. The processor (23) allows overlapping of detection results during the process of tracking the multiple detection targets.

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 generates, based on reference data, a group from multiple pieces of detected data generated based on the detection of the object, and generates representative data based on one or more pieces of detected data included in the group.

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.

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 heartbeat of a subject 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 forms a beam of the transmission wave in a direction of the subject to detect a heartbeat of the subject.

Abstract: An object tracking device and object tracking method that can track an object accurately without increasing the computational load are 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 execute a first process to select a Kalman filter with low certainty from among a plurality of the Kalman filters associated with the same detection target or observed value as an exclusion candidate Kalman filter that could be excluded from the association, and a second process to exclude from the association and initialize the exclusion candidate Kalman filter that meets an initialization condition.
