摘要： 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.

摘要： 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.

摘要： 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.

摘要： An information processing apparatus includes an input interface, a processor, and an output interface. The input interface obtains observation data obtained from an observation space. The processor detects a detection target included in the observation data. The processor maps coordinates of the detected detection target as coordinates of a detection target in a virtual space, tracks a position and a velocity of a material point indicating the detection target in the virtual space, and maps coordinates of the tracked material point in the virtual space as coordinates in a display space. The processor sequentially observes a size of the detection target in the display space and estimates a size of a detection target at a present time on a basis of observed values of a size of a detection target at the present time and estimated values of a size of a past detection target. The output interface outputs output information based on the coordinates of the material point mapped to the display space and the estimated size of the detection target.

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.

摘要： An information processing apparatus includes an input interface, a processor, and an output interface. The input interface obtains observation data obtained from an observation space. The processor detects a subject image of a detection target from the observation data, calculates a plurality of individual indices indicating degrees of reliability, each of which relates to at least identification information or measurement information regarding the detection target, and also calculates an integrated index, which is obtained by integrating a plurality of calculated individual indices. The output interface outputs the integrated index.
