基于遗传算法的圆柱阵列旁瓣电平优化方法

The Method of Optimizing Cylinder Arrays′SLL Based on Genetic Algorithm

由于共形阵列所具有的特性,使其正得到日益广泛的应用,但其方向图具有相对主瓣较高的旁瓣电平。为此,文章针对基本的共形阵列——圆柱阵列的天线阵元,应用经典遗传算法进行唯幅度的方向图综合,来优化旁瓣电平。仿真结果表明:该方法可有效降低圆柱阵列的旁瓣电平,为解决此类问题提供了有益的参考。

Conformal arrays are widely used because of their characteristic, but their sidelobe levels are high compared with the mainlobe levels. So this paper aims at the basic conformal arrays--cylinder arrays antenna modules, applys the classical genetic algorithm, carries on the amplitude -only pattern synthesis method to optimize the sidelobe level. The simulation result indicated： These methods may reduce the cylinder arrays＇sidelobe levels effectively, provide the beneficial reference to solve these kinds of problems.
