Abstract

The paper proposes a method for designing antenna arrays consisting of directional elements for direction-of-arrival estimation with super-resolution. Currently, wireless telecommunication systems mainly base their operation and significant indicators such as capacity and bit error rates on antenna arrays. As a rule, algorithms for processing signals from the outputs of the antenna channels have reached their maximum characteristics in terms of accuracy and resolution. It is known that the spatial pseudospectrum is strongly influenced by several factors, such as the relative position of antenna elements, their number and the shape of the radiation patterns. The statistical metric defined by the accuracy indicators is the Cramer — Rao lower bound. The previously obtained expression of the Cramer — Rao lower bound was used to achieve the target value of the variance of estimates, taking into account a given number of antennas by forming radiation patterns. The paper proposes a procedure for constructing antenna arrays for direction finding with superresolution. Arrays variants have been proposed, consisting of elements with a high gain, which compensate for the reduced number of antennas. Simulation studies have shown that the accuracy of the MUSIC algorithm increases when using the proposed and designed antenna arrays. Such indicators as the standard deviation depending on the spatial azimuthal coordinate, the directional coefficient of antenna elements for known geometries of circular arrays, as well as the proposed shapes were given. In addition, the results were confirmed by analytical expressions.
