摘 要: 针对基本免疫算法(immune algorithm,IA)多样性不理想、易陷入局部搜索导致早熟收敛的现象,提出模拟退火免疫算法(simulated annealing immune algorithm,SAIA)。引入退火选择算子,利用SAIA可以选择性接受恶化解的特点克服传统IA的缺陷。实验表明,应用这种改进算法,在阵列天线优化中能得到更低的旁瓣电平与零陷深度,验证了改进IA的优越性。
关 键 词: 微波技术;阵列天线;退火免疫算法;方向图综合;免疫算法

Abstract: In order to overcome the drawbacks of the basic immune algorithm (IA), such as prematurity and easily trapping in local optimum, simulated annealing immune algorithm (SAIA) is proposed. The introduction of annealing selecting operator can overcome defects of the traditional characteristics of IA by selectively accepting deteriorative solutions. Experiments show that the modified algorithm can achieve lower sidelobe level and null depth than the basic IA, which proves the superiority of the modified IA.
