Abstract
An antenna measurement device (2) that estimates an element electric field of a plurality of element antennas (11<sub>1</sub>) to (11<sub>M</sub>) in a transmission device (1) including an array antenna (10) including the element antennas (11<sub>1</sub>) to (11<sub>M</sub>) in which an excitation weight indicating an amplitude and a phase with respect to each of the plurality of element antennas (11<sub>1</sub>) to (11<sub>M</sub>) is changed, the antenna measurement device (2) including: a probe antenna (21) to receive a high-frequency signal radiated by the array antenna (10); a receiver (22) to detect a reception signal received by the probe antenna (21) and output an array response that is the detected reception signal in chronological order; and an element electric field estimating unit (23) to estimate an element electric field of each of the plurality of element antennas (11<sub>1</sub>) to (11<sub>M</sub>) using a Kalman filter that receives inputs of an array response output from the receiver (22) in chronological order and an excitation weight vector obtained by the excitation weight for each of the plurality of element antennas (11<sub>1</sub>) to (11<sub>M</sub>).
