基于小生境免疫算法的阵列天线方向图零点生成技术

内容简介：本文将小生境思想融入到免疫算法中，提出了一种小生境免疫算法。该算法对抗原识别后的抗体种群用小生境技术进行重构，将搜索空间划分为各自独立的小生境，并在各小生境内独立搜索，增强了抗体的多样性；引入小生境共享机制，用共享度控制抗体的促进和抑制，适当抑制高亲和度抗体的繁殖，克服了精英种群的冗余。将提出的小生境免疫算法（NDC_IA）应用于阵列天线方向图零点生成技术中，得到了较好的优化效果。

Abstract：In this paper, a niche immune algorithm is presented by combining niche idea with immune algorithm. The searching area is separated into several niches of antibody population and separated searching is processed in every niche in order to enhance searching efficiency and diversity of the antibodies. Sharing mechanism is introduced to the presented algorithm for antibody advancing and restraining in order to overcome the redundancy of excellent antibodies. The proposed niche immune algorithm （NDC_IGA） is applied in null steering of antenna array pattern synthesis for optimized results.
