In order to perform calibration of respective systems of an array antenna with high accuracy for adapting to a change in environmental condition, provided is a calibration device (20A) for calibrating an array antenna mounted on a satellite or the like, the calibration device including: a calibration coefficient calculating unit (21) to calculate a correlation of a plurality of input signals Xi(t,P), which are obtained by performing predetermined signal processing for signals received by an array antenna (11), to calculate weighting coefficients (²W) for calibrating systems of the array antenna; and a calibration executing unit (27) to calibrat the systems of the array antenna based on the weighting coefficients (²W).
