This analysis demonstrates the optimization of radiation patterns in phased array antennas, indicating improved performance in interference environments.
. This paper considers methods of adaptation to interference environment for a phased array antenna. A model of the radiation pattern (RP) of a linear equidistant antenna array in the horizontal plane is considered. The method of multi-objective optimization of the amplitude-phase distribution vector is analyzed. The following optimization quality indicators are described: the Euclidean norm of the difference between the reference RP and the calculated RP, the sum of the calculated RP levels at the interference points, and the maximum calculated RP level in the area of the side lobes. The results of the optimization algorithm are obtained. Graphs of the initial and optimized RP are presented, as well as a comparison to evaluate the performance of the third quality indicator.
