Abstract: A system includes a first device with a primary screening area; a second device with a secondary screening area different from the primary screening area; and processor circuitry. The first device includes a first antenna and a first communication device; the second device includes a second antenna and a second communication device. The first antenna irradiates an electromagnetic wave to a target in the primary screening area and receives an electromagnetic wave reflected by the target; the second antenna irradiates an electromagnetic wave to the target in the secondary screening area and receives an electromagnetic wave reflected by the target; and the processor circuitry determines a possibility that the target possesses a predetermined article, based on a level of the electromagnetic wave received by the first antenna, and determines that screening by the second device is required for the target in accordance with the possibility. The first communication device transmits, to the second device, first information identifying that screening by the second device is required for the target; and the processor circuitry makes the second antenna start irradiation of the electromagnetic wave when the second communication device receives the first information.

Abstract: According to one embodiment, an antenna device comprises an antenna panel including a first transmission antenna, a first reception antenna, and a second reception antenna, and a rotation device configured to rotate the antenna panel. A first radio wave is irradiated from the first transmission antenna when a rotation angle of the antenna panel is a first angle and a reflected radio wave of the first radio wave is received by the first reception antenna and the second reception antenna. A second radio wave is irradiated from the first transmission antenna when the rotation angle is a second angle and a reflected radio wave of the second radio wave is received by the first reception antenna and the second reception antenna.

Abstract: According to one embodiment, a system includes first to fourth transmission antennas, a plurality of reception antennas, and a processor. The processor is configured to acquire a first signal of radio waves which are transmitted by the first and third transmission antennas in a case where the measurement target is at a first position, acquire a second signal of radio waves which are transmitted by the second and fourth transmission antennas in a case where the measurement target is at a second position, and generate information of the measurement target by using the first and second signals. A first interval between the first and third transmission antennas and a second interval between the second and fourth transmission antennas are the same.
