1. A relay system for relaying radio waves between one or more wireless terminals and a base station, the relay system comprising:
one or more radiation units configured to form a beam in a predetermined direction by radiating radio waves from each of a plurality of elements;
one or more detection units configured to capture data other than radio waves, where the data is indicative of a physical environment on a radio wave propagation path that affects the beam formed by the radiation unit;
a direction determination unit configured to determine a direction in which the radiation unit should form the beam based on the physical environment detected by the detection unit;
a phase calculation unit configured to calculate a phase of radio waves to be radiated by each of the plurality of elements such that the radiation unit forms a beam in the direction determined by the direction determination unit; and
a phase control unit configured to control the phase of the radio waves radiated by each of the plurality of elements based on the phase calculated by the phase calculation unit.
