摘要
为降低光波导相控阵栅瓣提出阵元间距非均匀分布理论。利用MATLAB编写粒子群算法优化程序,对非均匀光波导阵列结构参数进行优化。仿真结果表明,非均匀阵元间距可以极大降低栅瓣强度。
The theory of the non-uniform distribution of the element spacing is proposed to reduce the influence of the grating lobes.The optimization program of PSO is prepared by MATLAB,and the parameters of non-uniform WOPA are optimized.MATLAB simulation results show that non-uniform distribution of the element spacing can greatly reduce the grating lobes intensity.
