Abstract: A image processing apparatus (20) includes at least an acquisition unit (210), a processing unit (220), and an image generation unit (230). The acquisition unit (210) acquires an intermediate frequency signal from an irradiation apparatus (10). The processing unit (220) generates three-dimensional positional information about a subject by processing the intermediate frequency signal. The image generation unit (230) generates at least a first two-dimensional image and a second two-dimensional image, and displays the two-dimensional images on a display apparatus (30). The first two-dimensional image is, for example, an image when viewed from a direction in which the subject moves, and the second two-dimensional image is, for example, an image when viewed from an opposite direction.

Abstract: There is provided an object identification apparatus for identifying a stationary object and a moving object. The object identification apparatus includes a phase difference calculator that calculates phase difference information between a transmission signal and a reception signal obtained by reflecting, by surfaces of the moving object and the stationary object in a space, the transmission signal emitted to the space and receiving the reflected transmission signal, a distance calculator that calculates distance information using the phase difference information, a distance information separator that separates the distance information into moving object distance information as distance information about the moving object and stationary object distance information as distance information about the stationary object, and an identifier that identifies the stationary object and the moving object based on the stationary object distance information and the moving object distance information.
