Abstract
A directional characteristic acquisition unitrotates a wireless terminalthat is a measurement target using a terminal holding rotation mechanismcentering around a standard point O, measures a field intensity Pr of a radio wave received by the measurement antennaat each rotation angle (ϕ, θ) to calculate a virtual directional characteristic of a terminal antennain the wireless terminal. An error information output unitcalculates a reception angle error (ϕ', θ′), a propagation loss error E, and a gain error Ethat occur in accordance with rotation of the wireless terminal, and corrects a virtual directional characteristic using these errors, using a correction unit, to calculate a directional characteristic Hc in a case where it is assumed that the terminal antennaof the wireless terminalis rotated at the position of the standard point O.
