Summary:In this paper we proposed a chaotic beamforming algorithm based on the optimization of the LMS algorithm using chaos theory, for the circular antenna array's radiation pattern synthesis. The goal of the beamforming algorithm's optimization using chaos theory is the fast adaptation of the antenna array radiation pattern on the concrete combination of received signals' angles of arrival, their most precise possible assessment, the setting of radiation diagram's deep nulls in the interfering signals' direction, the reduction of the radiation diagram's main lobe width, and the reduction of the side lobes.
