Abstract :
The problem of array measurement and calibration is addressed for the case in which the axes of rotation used during the measurement process are offset via a rotation and translation from the coordinate system that defines angle of arrival. A method for estimating the translation and rotation parameters from the measured data is presented, and the estimation/correction procedure is demonstrated on measured data.
