| 摘 要： | 由于圆形阵列所具有的特性，使其正得到日益广泛的应用，但是圆阵方向图却具有相对主瓣较高的旁瓣电平。为此，文中针对均匀圆形阵列的天线单元，应用差分进化算法，分别进行唯相位、唯幅度、相位一幅度的方向图综合方法，进行旁瓣电平的优化。仿真结果表明：这些方法可有效地降低圆阵的旁瓣电平，为解决此类问题提供了有益的参考。

| Abstract: | Circular arrays are widely used because of their pattern characteristics, but their sidelobe levels are high compared with the mainlobe level. For the antenna elements of uniform circular array, this paper applys differential evolution algorithm to optimize the sidelobe level by separately performing phase-only, amplitude-only, and phase-amplitude pattern synthesis. The simulation result indicates that these methods can reduce the sidelobe level of circle array effectively and provide a beneficial reference to solve these kinds of problems. |
