1. A system comprising:
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,
wherein:
the first device comprises a first antenna and a first communication device;
the second device comprises a second antenna and a second communication device;
the first antenna is configured to irradiate an electromagnetic wave to a target in the primary screening area and receive an electromagnetic wave reflected by the target;
the second antenna is configured to irradiate an electromagnetic wave to the target in the secondary screening area and receive an electromagnetic wave reflected by the target;
the processor circuitry is configured to determine a possibility that the target possesses a predetermined article, based on a level of the electromagnetic wave received by the first antenna, and determine that screening by the second device is required for the target in accordance with the possibility;
the first communication device is configured to transmit, to the second device, first information identifying that screening by the second device is required for the target;
the processor circuitry is configured to make the second antenna start irradiation of the electromagnetic wave when the second communication device receives the first information; and
an interval between irradiation points of the electromagnetic wave irradiated by the second antenna is shorter than an interval between irradiation points of the electromagnetic wave irradiated by the first antenna.
