Abstract :
An improved immune algorithm (IA) is proposed for pattern synthesis of linear antenna array with broad nulls steering. Gauss mutation and adaptive clonal scale control methods are presented to increase the antibodies´ diversity and enhance the global searching performance. In this paper, excitation amplitude of the array is setted as antibodies using realcode for steering broad nulls with specified width and at specified direction. Well simulatied results show the fine validity of the proposed algorithm.
