Antenna measurement device

An antenna measurement device that estimates an element electric field of a plurality of element antennas in a reception device including an array antenna including the element antennas in which an excitation weight indicating an amplitude and a phase with respect to each of the plurality of element antennas is changed, the antenna measurement device comprising:

• an element electric field estimator to detect a reception signal received by the array antenna and estimate an element electric field of each of the plurality of element antennas using a Kalman filter that receives inputs of an array response output in chronological order from a receiver that outputs an array response that is the detected reception signal in chronological order and an excitation weight vector obtained by the excitation weight for each of the plurality of element antennas.

An antenna measurement device that estimates an element electric field of a plurality of element antennas in a reception device including a phased array antenna including the element antennas in which a beam scanning weight with respect to each of the plurality of element antennas is changed, the antenna measurement device comprising:

• an element electric field estimator to detect a reception signal received by the phased array antenna and estimate an element electric field of each of the plurality of element antennas using a Kalman filter that receives inputs of an array response output in chronological order from a receiver that outputs an array response that is the detected reception signal in chronological order and a steering vector obtained by the beam scanning weight for each of the plurality of element antennas.
