The invention relates to a method for calibrating an antenna of a receiver of signals (s1, . . . , sN) originating from a plurality of sources, said receiver comprising a plurality of sensors (c1, . . . , cM), characterized in that it comprises the following steps: measurement of a phase shift (dm,n measure) for each of the sensors (c1, . . . , cM) on each of the signals (s1, . . . , sN), determination of at least one attitude value of the antenna, said attitude being defined by a set of coordinates, calculation, for each of the sensors on each of the signals, of a theoretical phase shift (dm,n theoretical) as a function of the attitude of the antenna, from the directions of arrival of the signals, calculation of a bias (β1 sensor m) for each of the sensors from the measured phase shifts (dm,n measure) and from the theoretical phase shifts (dm,n theoretical) of the sensor.
