  • Publication number: 20240027597
    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.
