Evaluation of angular coordinates of radio sources is a major research interest and is mainly used for the separation of objectives. The configurations used by antenna arrays, which have been studied mainly concerned uniform linear, uniform rectangular, circular and uniform. The main advantage for the LAR-finding tasks is narrow main lobe of the directivity pattern, but scanning is only possible in the azimuth plane. In problems that require both azimuth and elevation direction finding planar AR was used. To date, the work devoted to a comparative study with superresolution direction finding performance, including estimates of the boundary of the Cramer-Rao, different configurations for the AP, touch often only one or two types of. Therefore, to obtain the optimal shape of the antenna array, which allows to obtain estimates of target coordinates with the highest accuracy is very important.
