It is shown that the angular resolution of signal sources in phase direction finders with antenna systems in the form of linear arrays of weakly directed elements can be obtained by determining for each of its sources a set of complete periods of phase differences lost during measurements. It is shown that the maximum likelihood method developed to estimate the angle of arrival of a single signal is suitable for angular resolution of signals. The common grounds for angular resolution are shown by the maximum likelihood method and the “cosine summation” method. Estimates of the accuracy of direction finding of received signals.
phase direction finder, elimination of ambiguity, method of “cosine summation”, resolution
