The subspace algorithm based on eigenvalue decomposion is sensitive to the array misorientation, so it is necessary to calibration the error. The calibration source's direction-of-arrival and misorientation are studied in this paper. By using a single calibrate source without an exact knowledge of its direction of arrival and rotating the transmitting antenna's 90° around the z axis and x axis, and the array with misorientation receives the three signals whose directions of arrival have a special relationship. According to the subspace theory and the relationship between the Poynting vectors, the calibration source's direction and the array misoriention are precisely estimated.  Finally, simulation results verify the effectiveness of the algorithm.

Key words: direction of arrival estimation, array signal processing, vector sensor arrays, calibration
