COMPERATIVE ANALYSIS OF ANTENNA ARRAY CALIBRATION METHODS

The paper presents a comparative analysis of antenna array calibration methods aimed at compensating geometric inaccuracies arising in real systems. Two main approaches are considered: the method of global calibration with the use of pilot sources, which allows by solving a system of equations to correct the array parameters, and the self-calibration algorithm, designed to determine the directions of arrival of signals, which by analyzing the covariance matrix analysis to identify and compensate for errors in the system’s geometry.
