    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: An electronic device includes a transmission antenna, a reception antenna, 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 signal processor is configured to detect an object based on a transmission signal transmitted as the transmission wave and a reception signal received as the reflection wave. The signal processor is configured to output information regarding a point group representing the position of an object determined to be a stationary object based on the velocity of the object and the velocity of the electronic device.

    Abstract: An electronic device comprises a transmitting antenna that transmits a transmitted wave, a receiving antenna that receives a reflected wave obtained by reflection of the transmitted wave, and a controller. The controller generates a first sample based on a result obtained by subjecting a beat signal generated based on a transmitted signal based on the transmitted wave and a received signal based on the reflected wave to a first fast Fourier transform process. The controller generates a second sample based on a result obtained by subjecting the first sample to a second fast Fourier transform process, and estimates an arrival direction of the reflected wave based on the second sample. The controller sets the first sample from the beat signals in which the peak in the result obtained by performing the first fast Fourier transform process is equal to or higher than a first threshold value.

    CPC classification number: G06T7/277

    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.

    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) groups a plurality of the Kalman filters and determines whether or not each of the Kalman filters corresponds to an identical object.

    Abstract: An electronic device includes a transmission antenna, a reception antenna, and a signal processor. The transmission antenna is configured to transmit a transmission wave. The reception antenna is configured to receive a reception wave resulting from reflection of the transmission wave. The signal processor is configured to detect an object, with a constant false error rate, based on a transmission signal transmitted as the transmission wave and a reception signal received as the reflection wave, The signal processor selects, based on a maximum likelihood estimated value that gives a false alarm rate of signal intensity based on the reception signal, a reference cell disposed in a distance direction with respect to an inspection cell in a two-dimensional distribution of signal intensity, based on the reception signal, in the distance direction and a relative velocity direction.
