Classification: CPC H  Y | IPC H

Claim 9:
10. A method of acquiring the first intensity ratio table and the second intensity ratio table used in the polarization direction measuring device according to claim 1, the method comprising:
setting up a radio wave source for generating the received wave so that the received wave is in a predetermined arrival direction and has a predetermined polarization with respect to the plurality of circularly polarized antennas;
causing the radio wave source to generate the received wave;
receiving the received wave with the plurality of circularly polarized antennas; and
acquiring the first intensity ratio table in which the first intensity ratio of a vertically polarized component of the received wave between two of the circularly polarized antennas is associated with an arrival direction of the received wave, and the second intensity ratio table in which the second intensity ratio of a horizontally polarized component of the received wave between the two circularly polarized antennas is associated with an arrival direction of the received wave.
