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 set a range of detection of the object, for each frame of the transmission waves.

Abstract: An electronic apparatus includes a controller configured to control switching between a first mode in which radiation of transmission waves is directed in a first direction and a second mode in which radiation of transmission waves is directed in a second direction downward from the first direction. When a predetermined status is detected in the first mode, the controller performs control to switch to the second mode.

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 detects an object reflecting transmitted waves based on transmitted signals transmitted as the transmitted waves from transmitting antennas and received signals received from receiving antennas as reflected waves obtained by reflection of the transmitted waves. The electronic device determines that the object have been detected when the peak in the result obtained by performing a Fourier transform process on the beat signals generated based on the transmitted and received signals is equal to or higher than a predetermined threshold value. The electronic device sets a predetermined threshold value based on an object detection probability.

Abstract: An electronic apparatus includes a transmission unit, a reception unit, and a controller. The transmission unit transmits a transmission wave. The reception unit receives a reflected wave of the transmission wave reflected by an object. The controller operates the transmission unit in one of a plurality of operation modes having different detection distances. When the reflected wave is received by the reception unit, the controller determines a distance between the electronic apparatus and the object, based on the transmission wave and the reflected wave. The controller operates the transmission unit in an operation mode having the detection distance that includes the distance to the object and is the shortest, from among the plurality of operation modes.
