基于遗传算法的圆柱阵列稀疏方法

由于共形阵列所具有的特性,使其正得到日益广泛的应用,但其耗用较多的阵元,方向图具有相对主瓣较高的旁瓣电平。为此,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,以阵元的工作状态为优化参量,对其进行稀疏。减少了阵元数量,仿真结果表明,该方法能有效地降低圆柱阵列的旁瓣电平。

A thin cylinder arrays method based on genetic algorithm

Conformal arrays are widely used because of their characteristic,but they consume many array elements and 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 ,sets the working sate of elements as variables, reduces the element number to thin them. The simulation results show that the method may reduce the cylinder arrays sidelobe levels effectively.
