<P>PROBLEM TO BE SOLVED: To provide an electromagnetic wave measuring apparatus which is capable of accurately evaluating electromagnetic wave scattering in a far field while using electromagnetic wave scattering data measured in a near field. <P>SOLUTION: An electromagnetic wave measuring apparatus comprises a housing 3 including a radio wave absorber 4, an NF antenna 5 which is provided within the housing 3 and transmits spherical waves/electromagnetic waves to a measurement area 11 in which an airplane model 15 that is a scaled-down model, and receives scattered waves, and a compact range 9 which is provided within the housing 3 and converts the spherical waves/electromagnetic waves into waves/electromagnetic waves. The apparatus further comprises an FF antenna 7 which transmits the converted waves/electromagnetic waves to the measurement area 11 and receives scattered waves, and data converting means which converts measurement data obtained by the NF antenna 5 into data which can be contrasted with measurement data obtained by the FF antenna 7. <P>COPYRIGHT: (C)2013,JPO&INPIT |
