Phase adjustment control device of phased array antenna, array antenna device, antenna measuring device and phase adjustment method of phased array antenna

摘要

Even if all the element antennas do not radiate radio waves at the same time, an array antenna device capable of performing the same calibration as in the case where all the element antennas are in an operating state is obtained. Divide the plurality of element antennas 1 into the element antenna group 10, and in turn the operating element antenna set 20 including the at least two element antenna groups 10 including the measured element antenna group 10 The operation is made. In the element antenna set 20 of the element electric field vector of the element electric field vector which the element antenna 1 which changes the phase and changes the phase using the several received electric power value of the electric wave radiated | emitted in a different phase by changing the phase of the element antenna 1, Different operations are performed using the element electric field calculating circuit 11 for calculating the phase difference in the set of and the element electric field vector of the element antenna 1 whose element electric field vector is calculated using the plurality of different operating element antenna sets 20. The phase difference calculation part 16 which calculates the phase difference of the element electric field vector of the element antenna 1 which belongs to the element antenna set 20 is provided.
