摘要
针对标准差分进化算法早熟收敛和局部搜索能力差的缺陷,采用一种改进的差分进化算法综合非均匀线阵。该算法在计算过程中自适应调整缩放因子和交叉概率因子,以非均匀阵列天线的阵元间距为优化变量,实现了阵列的最大峰值旁瓣电平的有效控制。仿真结果表明:该改进算法可应用非均匀天线阵列的综合,并取得良好的优化结果,简单实用,快速方便,鲁棒性和稳定性好。
In order to solve the problem of premature convergence and poor local searching ability in the differential evolution（DE） algorithm,a modified differential evolution algorithm was applied to optimize the spacing between the elements of the non-uniform arrays.It adjusted scale factor and crossover rate adaptively according to the computation process,made the adjustable mini-mum element spacing as optimization variable of non-uniform antenna array to control the peak side-lobe level.Simulation results showed that the algorithm was of reliable,effective,stable and high robustness for synthesis of non-uniform arrays.
