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，本文针对均匀圆形阵列的天线单元，应用遗传算法,分别

进行唯相位、唯幅度、相位-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。 -Circular array of features, are being increasingly widely used, but the circular array pattern with the relative main lobe higher sidelobe level. This uniform circular array antenna unit, the application of genetic algorithms, respectively, the only phase, only the amplitude, phase- the magnitude of pattern synthesis method, the sidelobe level optimization. The simulation results show that: these methods can effectively reduce the circular array sidelobe level to solve such problems provide a useful reference.
