摘 要: | 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。

Abstract: | 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. |
