Array antenna device, antenna measurement device, phased array antenna phase adjustment method, and phase adjustment control device

摘要

Calibration is performed so that the phase reference of each element antenna is aligned even if all the element antennas do not emit radio waves simultaneously. A plurality of element antennas (1) are divided into element antenna groups (10), an operating element antenna set (20) including at least two element antenna groups (10) including a measured element antenna group (10) is sequentially set in an operating state, and allowable radiated power is obtained. Radiates radio waves within the range of values. Among the operating element antenna sets 20 of the element electric field vector generated by the element antenna 1 that changes the phase by using the plurality of received power values of radio waves radiated in different phases by changing the phase of the element antenna 1. Using the element electric field vector of the element antenna 1 which calculated the element electric field vector using the element electric field calculation circuit 11 for calculating the phase difference within the set and the plurality of different operation element antenna sets 20, different operating element antenna sets 20 And a phase difference calculation unit 16 for calculating the phase difference of the element electric field vectors of the element antennas 1 belonging to.
