A description has been provided of a mathematical model for a non-equidistant linear antenna array with quasi-symmetric phase center placement, followed by optimization of its parameters through numerical simulation. It has been shown that switching to a non-equidistant linear antenna array not only achieves results comparable to those obtained using a Dolph-Chebyshev array but also provides additional opportunities for effective main lobe extraction in the radiation pattern against the background of sidelobes. The proposed multiparameter optimization technique allows flexible adjustment of the antenna system's characteristics based on specific user requirements and resource constraints, opening broad prospects for practical applications in various fields of radio engineering and telecommunications. As a result of the study on the non-equidistant linear antenna array, a new method for determining the main lobe has been proposed, significantly expanding the possibilities for more accurate estimation of the probability of anomalous errors in radio direction finding. This enhances the ability to predict potentially achievable characteristics of wide-frequency-range direction finders that incorporate linear antenna arrays in their architecture.
