|発明の名称||NEAR-FIELD MEASURING DEVICE AND NEAR-FIELD MEASURING METHOD|
PROBLEM TO BE SOLVED: To provide a near-field measuring device and a near-field measuring method with which it is possible to acquire an amplitude distribution and phase distribution over a wide range in the near field of an antenna to be measured without switching a measurement signal.
SOLUTION: The near-field measuring device comprises: a probe antenna 12 for receiving a multi-carrier signal transmitted from an antenna 100 to be measured; a receive unit 15 for converting, for each scan line, the multi-carrier signal received by the probe antenna 12 into a digital complex baseband signal; a storage unit 16 for storing the complex baseband signal in association with the position of the probe antenna 12 on a measurement plane P when the multi-carrier signal is received by the probe antenna 12; an extraction unit 17 for extracting an RS included in a plurality of sub-carriers from the complex baseband signal stored in the storage unit 16; and an amplitude phase change amount calculation unit 18 for calculating an amplitude fluctuation amount and a phase fluctuation amount of the RS extracted by the extraction unit 17.
