Abstract: Angular resolution method of signal sources in phase direction finders with antenna systems in the form of linear, flat or three-dimensional arrays consisting of weakly directed elements is considered. The angular resolution of the signals is achieved by determining for each of the sources its own set of full periods of phase differences lost during measurements. It is shown that the maximum likelihood method developed for estimating the angle of arrival of a single signal is suitable for angular resolution of signals. There is given the received signals bearing angle accuracy evaluation.

Keywords: phase direction finder, phase difference, angular resolution, maximum likelihood estimation

Funding: The work was carried out within the framework of a state assignment from the Ministry of Education and Science of the Russian Federation, project No. FEWM-2023-0014.
