Abstract
We present a mathematical formalization and the results of computer simulation of an angular phase discriminator, which employs a linear antenna array with adaptation according to the Howells–Applebaum algorithm. A method of improving the direction-finding accuracy of the radio-emission sources, which provides the measurement unambiguity with a considerable increase in the measurement baseline, is proposed. The limiting values of the measurement baseline are determined with allowance for the unambiguity preservation in the case of an increase in the element number in the antenna array and a comparison of the slope of the direction-finding characteristics of the standard and proposed phase direction finders is performed with an admissible increase in the unambiguous-baseline sizes.
