基于二进制BMO算法的稀疏直线阵列方向图综合

Synthesis of thinned line array based on binary butterfly mating optimization

针对蝴蝶交配优化算法(butterfly mating optimization,BMO)无法处理离散的问题,首先提出了一种二进制蝴蝶交配优化(binary butterfly mating optimization,BBMO)算法,并将该算法应用到阵列天线的稀疏优化设计中;然后,以最大副瓣电平为优化目标,对100元直线阵进行了稀疏,优化后得到的最大副瓣电平为-21.28dB,稀疏比例为24%,优化结果好于GA、ACO、BDE、BPSO等算法,证明了该算法的优越性。

As the discrete problem can not be dealt with by butterfly mating optimization（BMO）,a binary butterfly mating optimization（BBMO）is proposed and applied to the pattern synthesis of thinned antenna array.A linear array with 100 elements is optimized by BBMO algorithm in order to reduce the maximum side lobe level.The optimal maximum side lobe level is 21.28 dB,and sparse proportion is 24%.Calculation results show that the proposed algorithm obtains better solutions than the other algorithms,such as GA,ACO,BDE and BPSO.
