Abstract
Different approaches to the problem of estimation of the direction of arrival of the incident wave with an unknown polarization are considered. It is found that the obtained solutions can be used to increase the accuracy and reliability of direction finding due to elimination of polarization errors and to determine the polarization parameters as an additional information parameter. Analysis of the results obtained for a particular configuration of the antenna array is performed. It is shown that the proposed method is more efficient for determination of the direction to the source of an arbitrarily polarized electromagnetic field than the approaches oriented to processing of the field with a predetermined polarization. The results of a numerical simulation confirming these conclusions are presented.
