<p><P>PROBLEM TO BE SOLVED: To improve measurement precision by avoiding influences of directivity that a transmit antenna has. <P>SOLUTION: A radio wave transmitter/receiver (4) is used for which directivity of a transmit antenna (16) is fixed with respect to a receive antenna (14) by sharing a confronted surface (56) of the transmit antenna with respect to the receive antenna. The radio wave transmitter/receiver is moved on a specific spherical surface and a radio wave (20) radiated from the transmit antenna is received by the receive antenna. In arithmetic means (arithmetic unit 10), a receiving level of the receive antenna is compared with a receiving level which is given by a theoretical formula of the receiving level, thereby obtaining deviation depending on a measuring place where the radio wave transmitter/receiver is installed. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
