针对扫描范围有限的共形阵列天线,在保证天线孔径不变的情况下,基于遗传算法提出了以天线开关矩阵为变量,以最大副瓣电平最小化为优化目标的优化算法。仿真结果表明,该方法可以有效降低天线副瓣电平,提升阵列优化效率。

Aiming at the conformal array antenna with limited scan scope,in the state that the an- tenna aperture is unvarying, this paper proposes the optimization method based on generic algo- rithm, which takes the antenna on-off matrix as variable and the minimum of maximal side lobe lev- el as the optimal object. Simulation results show that the proposed algorithm can effectively reduce the side lobe level of antenna and improve the array-optimizing efficiency.
